chore: instantly refill the pipeline on flush
...
I believe this to be necessary in order to get hardware interrupts
working.
thumb.gba test 108 fails but I'm committing anyways (despite the
regression) because this is kind of rebase/merge hell and I have
something that at least sort of works rn

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%

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

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.

are in read/write functions and deinits

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
