Fix the global checksum calculation in rgbfix

Browse Source 
A regression was spotted in rgbfix 0.3.7, where we would accidentally include the first byte of the existing checksum when calculating a global checksum. We now correctly ignore both of the existing checksum bytes.

This was spotted when running rgbfix on the Pokémon Gold/Silver betas, as they have a non-zero global checksum.

Fixes #280.
