Support dynamic initialization of optional dependencies

:recycle: Current situation & Problem

Optional dependencies are already supported by Spezi. However, they lack the ability to dynamically supply a default value. Currently, you can only declare an optional dependency and check if it was configured e.g. by the user. But it wasn't possible to provide a default value (e.g., behind some runtime check) yourself.

:gear: Release Notes

• Add support to dynamically provide a default value for optional dependencies.

:books: Documentation

Documentation was added and updated.

:white_check_mark: Testing

Extensive testing was added for the new initializer, testing all possible combinations of initialization.
