Version 2.0 release, including progress tracking.

Pre-calculating CAPICE scores can be error sensitive, both machine could crash or a (slurm) job could be cancelled.

• Added progress_tracking.py to keep track of the progression.
• If no progress json is found, but an output file is found, it will try to backtrack the progress.
• More Object Orientated program structure.
• Bugfixes (like assuming the given model is a RandomSearchSV object)
