Enforce BaseExperiment abstract methods

[drbenvincent]

Summary

• make BaseExperiment inherit from ABC and relax abstract requirements based on supports flags
• add explicit method stubs to experiments missing required abstract methods
• add a test to enforce abstract-method instantiation failures

Testing

• conda run -n CausalPy python -m pytest causalpy/tests/test_base_experiment_abc.py (fails: coverage fail-under=80 when running single test)

Closes #660
