Sentinelhub

- (**codebreaking**) Adapted Sentinel Hub tasks to `sentinelhub-py 3.8.0` which switched to Catalog 1.0.0.
- (**codebreaking**) Removed support for loading pickled objects in EOPatches (deprecated since version 1.0.0).
- (**codebreaking**) Various improvements of `FeatureIO` class. Only affects direct use of class.
- Added type annotations to majority of `eolearn.core`. The types are now exposed via `py.typed` file, which enables use of `mypy`. Added type-checking to CI for the `core` module.
- Numpy-array based features can now save and load `object` populated arrays.
- Improved documentation building, fixed links to GitHub.
- Improved test coverage.
- Added pre-commit hooks to repository for easier development.
- Various minor improvements.

- Corrected the default for `no_data_value` in `ImportFromTiffTask` and `ExportToTiffTask` to `None`. The previous default of `0` was a poor choice in many scenarios. The switch might alter behavior in existing code.
- Changed the way `SpatialResizeTask` accepts parameters for the final image size. Now supports resizing by using resolution.
- Added `ExplodeBandsTask` that explodes a multi-band feature into multiple features.
- Exposed resampling parameters in Sentinel Hub tasks and included a `geometry` execution parameter.
- Reworked internal classes `FeatureIO` and `_FeatureDict` to improve types and maintainability.
- Fixed y-axis orientation of `MeteoblueRasterTask`.
- `FilterTimeSeriesTask` adjusted to work with multiprocessing.
- EOPatch plotting no longer anti-aliases by default (removes issues with phantom values in mask plots)
- Improved documentation building, fixing a few broken links.

- Improved handling of filesystem objects:
* introduced utility functions `pickle_fs` and `unpickle_fs` into `eo-learn-core`,
* updated all IO tasks to fully support `filesystem` as an `__init__` parameter,
* updated `EOExecutor` to support `filesystem` propagation to worker processes.
- Official support for Python `3.10`.
- Moved `eolearn.coregistration.ThunderRegistrationTask` into an extension of `eo-learn-coregistration` package because it doesn't support Python `3.10`.
- Updated functionality of `eolearn.features.SimpleFilterTask`. It now returns a new `EOPatch` and doesn't raise an error if all time slices would be filtered out.
- Larger updates of `eolearn.io.ExportToTiffTask`. It doesn't allow undefined `folder` parameter anymore, but it has better support for `filesystem` objects.
- Added `eolearn.core.utils.raster.fast_nanpercentile` utility function and moved `constant_pad` function into the same module.
- Suppressed a warning when saving an `EOPatch` with empty vector features.
- Updated code-style checkers by including `flake8` and checks for Jupyter notebooks.
- Various style improvements in example notebooks, code, and tests.

- Fixed a bug in `eolearn.io.ImportFromTiffTask` where a bounding box from the image wasn't added to the EOPatch.
- Increased minimal version of `Pillow` dependency in `eolearn.features`.

- Large improvements of parallelization in EOExecutor. Introduced the `eolearn.core.utils.parallelize` module, featuring tools for different parallelization modes.
- Added support for session sharing in `SentinelHubInputTask`, `SentinelHubEvalscriptTask` and `SentinelHubDemTask` by adding a `session_loader` parameter. Session sharing of `sentinelhub-py` is explained [here](https://github.com/sentinel-hub/sentinelhub-py/blob/master/examples/session_sharing.ipynb).
- Added `SpatialResizeTask` to `eolearn.features.feature_manipulation` for spatially resizing EOPatch features.
- Improved how `ImportFromTiffTask` reads from remote filesystems.
- Switched to non-structural hashing of `EONode` class to avoid massive slowdowns in large workflows.
- Improved procedure for building documentation and displaying of type annotations.
- Various minor improvements.

- Added workaround for an issue introduced by `fs==2.4.16`.
- Executor progress bar improved for use-cases with many EOPatches.
- `LoadTask` and `SaveTask` can now handle *empty* queries (by setting `eopatch_folder=None`).
- Minor improvements in code and documentation.
