Large pnaches cause crashes due to patches overwriting game data

[TheOnlyZac]

If the strings or the assembly code being patched in is too long, it will lead to unusual behavior or game crashes.

Planned solution

• Add an additional assembly function that performs a sanity check to ensure there are enough null bytes to write all the strings/machine code bytes.
• Add a conditional to the final pnach that only writes the bytes if the sanity check passed.
