feat: assemble the naomi.zip demul reads

Demul 0.7 reads 44 NAOMI BIOS rows from naomi.zip, the HOTD2, F355 and Airline Pilots BIOS among them. No copy held them all. The set is built with build_torrentzip from members already in the collection, each checked against the crc32 and sha1 of demul.exe's table, and kept in bios/Other/demul/. Batocera, KNULLI and RetroBat place it at bios/naomi.zip, the file MAME cores there also open, so it carries the nine MAME members the Demul table does not list.

The resolver left another emulator's own copy out of the member and superset ranking, so Flycast and the MAME cores keep the copies they were served.
