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.

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
