Rom stamping

Implemented ROM Stamping feature for debugging purposes.

I have reserved 350 bytes starting at 1B A000 to store the following information about the rom

• Seed (64 bytes)
• Encoded Flag String (158 bytes)
• Git SHA used to generate the ROM, full size reserved (40 Bytes)
• SHA-1 of the input rom (40 Bytes)
• Filler (48 Bytes) The filler is currently just writting 48 spaces as a reserve incase the ROM stamp needs to be bigger.

I got distracted and made a mistake with this merge, will fix and comment.

• [x] git-blame my kids

ok, this can be reviewed now XD turns out my Visual Studio is now broken, so I am ok with this for now lol

here we go again!
