skchange integration - base class homogenization

[fkiraly]

As described in issue https://github.com/sktime/sktime/issues/7323

I have carried out the most significant parts on the base class level here: https://github.com/sktime/sktime/pull/7342

What remains is:

• changes to the transform method, to be discussed
• go through individual classes inheriting from BaseDetector (after this PR) and ensure they comply with the new homogenized interface definitions. There will likely be small issues for each class. As #105 progresses, the tests will likely flag up incompatibilities with the API which also need to be fixed.
• ensure this is aligned with changes to the test framework, see https://github.com/RobotPsychologist/bg_control/issues/105

Once this is done, we can make changes within skchange itself:

• skchange to use the BaseDetector from sktime as base class where possible
• skchange to use the parametrize_with_checks utility from sktime for testing. This is conditional on #105.
