Add support for Touhou 20 Fossilized Wonders 1.00a

[Dimmitsaras]

• Add Th20 1.00a support
• Add module base address to support use of memory relative offset addresses (as used in th20)

-I could not find ENEMY_STATE_POINTER so i scrapped the whole fighting midboss logic
-Shot type only displays the main story stone as R1, R2, B1 etc

Don't know if there's any more specifics to do on the discord side of things, it works in my testing.

Hello and thank you for your contribution!
I didn't touch Fossilized Wonders yet, so I can't test your integration by myself to ensure everything works out. I'll try to check this out when I can.
Sorry for the delay! I'll keep you up-to-date once I got this tested, then I can get in the more technical side of the review.

No worries friend, take your time!
