Rekai Nyangadzayi Musuka 65cfc97f28 feat: reimplement audio sync
APU will now drop samples if the Audio Queue is already full, therefore
creating a "sped-up" effect when the emulator runs faster than 100%

Rekai Nyangadzayi Musuka 59669ba3a5 chore: rename arm7tdmi variables to just cpu
Less verbose, specifying arm7tdmi doesn't really do much when there's
no other CPU in the system

Rekai Nyangadzayi Musuka 6a798d2c9d chore: allocate sprite array on heap
Each Sprite optional is 10 bytes meaning I'm allocating 1.28Kb on the
stack which isn't necessary.

Rekai Nyangadzayi Musuka e57f918856 chore: pass the allocator as an argument more often

Rekai Nyangadzayi Musuka e5b7441740 fix: resolve use-afer-free in backup.zig
This worked fine on stage1, and works fine in debug in stage3.
However, stage3 ReleaseSafe would panic due to what I assume must
have been an undefined behaviour optimization.

While I'm happy that I was quickly made aware of the issue thanks to
the safety checks in ReleaseSafe I do wish that this issue showed itself
in Debug, since I *am* using the GPA
