Inseminator

- upgrade test requirements
- fix function decorators

- `inject` method is now lazy in the evaluation and constructs dependencies in the call-time
- injected function can now be called with position and kw-args and dependencies independently of the position of the dependency parameter

now mypy will recognize inseminator during the static analysis

The resolver is now able to automatically construct `BaseSettings` object specified as a dependency.

Default parameter values are now taken into account when resolving a dependency.
