Simputils-config

* Added `names()` class method to `simputils.config.generic.BasicConfigEnum`
* Decreased acceptable Cyclomatic Complexity level
from 10 to 5 in the project (for better code quality control)
* Removed unnecessary dependency of `typing_extensions`
* Ticket https://github.com/PandaHugMonster/py-simputils-config/issues/21
* Implemented flag and functionality for strict set of keys
* If enabled, and unknown key is accessed the `simputils.config.exceptions.StrictKeysEnabled` exception
is raised
* Fixed a small bug with some minimal preprocessing when getting value by the "key".
Now all the provided keys are passing the `preprocessor` to conform with the rules.
* Ticket https://github.com/PandaHugMonster/py-simputils-config/issues/29
* Added document [Working with ConfigHub](working-with-config-hub.md)
* Implemented "Conditional Config", callables for `ConfigHub.aggregate()`
* Documentation can be found here: [Working with ConfigHub](working-with-config-hub.mdconditional-config)
* Simple support for `ExecEnv` aka "Stage" through "Conditional Config"
* Ticket https://github.com/PandaHugMonster/py-simputils-config/issues/20
* Implemented `simputils.config.components.prisms.ObjConfigStorePrism` for `ConfigStore`.
It allows to use "Config Object Style Access" for accessing key/value pairs through `obj` field of `ConfigStore` object.
* And documentation for it: [Config Object Style Access](config-object-style-access.md)
* Ticket https://github.com/PandaHugMonster/py-simputils-config/issues/32
* Improved compatibility with [pydantic](https://docs.pydantic.dev/latest/) models
* Now pydantic models can be used as `type` for Enum Config annotations, then the structures
will be converted accordingly. Useful especially with "Config Object Style Access" aka `ConfigStore.obj`
* Documentation can be found here: [Pydantic Integration](pydantic-integration.md)
* Implemented proper `type` processing of union types for Config Enum annotations
* Ticket https://github.com/PandaHugMonster/py-simputils-config/issues/25
* Prepared documentation and schemes for all strategies: [Config Merging Strategies](config-merging-strategies.md)
* Polished the concept of Merging Strategies (see schemes in [schemes/images](schemes/images))
* Implemented general Merging Strategies infrastructure
* "Implemented" Flat Strategy (teeny-tiny class of couple lines)
* Ticket https://github.com/PandaHugMonster/py-simputils-config/issues/23
* Implemented Recursive Merging Strategy `simputils.config.components.strategies.MergingStrategyRecursive`
* With params to **replace lists** (default) or **extend lists**
* Recursive merge of objects like "pydantic models" is supported
* Recursive merge of other objects is supported (like `dataclasses`, etc.) but might not
be fully out of the box working as expected
* Added additional unit-tests (for combination of recursive merging strategy and pydantic integration)
* Updated documentation about Merging Strategies in general, and about Recursive Merging Strategy
* Can be found here: [Config Merging Strategies](config-merging-strategies.md)

* Fixed missing dependency of `typing_extensions`

* Improved `Enum` usage with configs 13
* Documentation here [working-with-enums-and-annotations.md](working-with-enums-and-annotations.md)
* Implemented `simputils.config.base.get_enum_defaults()`
method to get default values form `Enum` class
* Implemented `simputils.config.base.get_enum_annotation_for()`
method to get specific annotation for specific key of `Enum`
* Implemented `simputils.config.base.get_enum_all_annotations()`
method to get all available annotations of `Enum`
* Added `ENUM` key to `simputils.config.enums.ConfigStoreType`
* Implemented `simputils.config.generic.BasicConfigEnum.target_config()` shortcut
* Added support of `Enum` class for `simputils.config.generic.BasicConfigStore`.
So you can specify a raw class reference as a source of config
* Added `type` field to `simputils.config.models.AnnotatedConfigData` for type casting
* Added disclaimer [Potential package collision 2024](disclaimers.md)
* Some more cleanups and small improvements
* Improved preprocessors infrastructure and added type auto-casting for strings 11
* Improved `simputils.config.base.simputils_pp()`
function through class `simputils.config.components.preprocessors.SimputilsStandardPreprocessor`
* Added `simputils.config.base.simputils_cast()` for auto-casting strings
* Added `simputils.config.base.simputils_pp_with_cast()` for standard simputils key
normalization auto-casting strings
* Implemented `simputils.config.components.preprocessors.SimputilsCastingPreprocessor` auto-casting preprocessor
* Implemented `simputils.config.components.preprocessors.SimputilsStandardPreprocessor` key normalization
(just code relocation from `simputils.config.base.simputils_pp()`)
* Implemented `simputils.config.generic.BasicPreprocessor`
* Added documentation about preprocessing and filtering:
[Preprocessing and filtering](preprocessing-and-filtering.md)
* Now `list` or `tuple` with callables can be provided to the `preprocessor` param,
which sequentially will be applied to incoming key-value pairs.

* Added `simputils.config.generic.BasicConfigEnum.get_annotation_for()` class method
* Added initial documentation about `Enum`
usage [working-with-enums-and-annotations.md](working-with-enums-and-annotations.md)
* Improved some documentation [../README.md](../README.md)
* Added automated tests for `Enum` annotations in `tests.unit.TestConfigStore`

* Improved type hints and fixed typing in general in the code.
* This python module for reference `simputils.config.types`
* Extracted basic functionality from `simputils.config.models.ConfigStore` to
`simputils.config.generic.BasicConfigStore` in fully backward-compatible way
* Extracted basic fields from `simputils.config.models.AppliedConf` to
`simputils.config.generic.BasicAppliedConf` in fully backward-compatible way
* Improved some of `simputils.config.generic.BasicConfigStore` functionality
* Added `ARGPARSER_NAMESPACE` key to `simputils.config.enums.ConfigStoreType`
* Some general code cleanups and code format improvement
* Improved some documentation [../README.md](../README.md)
* `Enum` support added:
* Added abstract `simputils.config.generic.BasicConfigEnum` class
* Added `simputils.config.models.AnnotatedConfigData` annotation class for enums
* For documentation about this feature refer
to [working-with-enums-and-annotations.md](working-with-enums-and-annotations.md)

* Some tini-tiny improvements
