Crashes on parsing database

[kitchenknif]

Script crashes when parsing database because catalog starts with a "DIVIDER" entry.

added in the for-loop of getMaterialFilename() to fix:
if 'DIVIDER' in sh: continue

Also data is in data/ folder not data-nk/, at least in my git cloned version of the database

@kitchenknif I’ve been rewriting it with substantial help from Claude Code recently. The codebase is now simpler and should work as expected. The updated version is available on PyPI. Please check if it works for you
