MaddoScientisto 4d3c8cd81b Add detailed class event processing and family comparison tools 
- Enhance `extract_eusecode_flx.py` to derive class event rows with additional metadata including derived body windows and repeated template statuses.
- Introduce `usecode_family_compare.py` for comparing event families, analyzing commonalities in event bodies, and generating reports on identical groups and differences.
- Implement new data structures for managing class event rows and family artifact specifications.
- Update output formats to include derived body information and repeated family regression checks.
- Ensure robust validation of repeated family expectations against actual extracted data.

Environmental Family Decompiled Event Sketches

This is a reversible per-class rendering derived directly from class_event_index.tsv plus the raw extracted chunk bytes. ScummVM event labels remain hints only; the authoritative data here is the slot id, raw row bytes, and derived body window.
