Filter out Max Raid den routes from Sword/Shield game data

Den child routes (~561 per game) bloated the route list without being
useful for Nuzlocke tracking. Adds filter_den_routes() to strip children
matching "(Den " from the route hierarchy, reducing Sw/Sh from ~1,007
to 446 routes each.

+Sword/Shield game JSONs contain ~561 den child routes out of ~1,007 total entries (~56%). These are Max Raid Battle dens named like '(Den I - ...)'. Add a filter_den_routes() function in processing.py and call it in __main__.py for sword-shield only, then re-run the import.
