Add NeoGeo CD

[niemasd]

I should add NeoGeo CD support

[niemasd]

I can't seem to figure out how to parse Neo Geo CD discs. I'll need some help with this. Some potentially useful resources:

• https://github.com/finalburnneo/FBNeo/blob/master/src/burner/win32/neocdlist.cpp
• https://github.com/niuus/NeoCDRX/blob/main/src/cdrom/cdrom.c

Actually, they seem to be ISO 9660 discs. The PVD isn't at the usual location, but I can change the GameID.ISO9660 class to search for the CD001 signature of the PVD instead of hardcoding the position
