Better framedata readings + Stability Improvements

• Gaps are now added with 1F more to avoid confusion with an obsolete convention
• Lots of stance attacks are now considered "not idle" (Faust pogo, Chipp wallcling, etc.), as well as some particular animations' recovery portions like Ram 5PPP and blitz
• Handles switching characters in training mode, without crashing
• Better tracking of which player is which character (Sol, Ky, etc.)
• Less CPU consumption

Huge thanks to @kkots for all these improvements!
