Fix size inconsistency for prg and chr

Browse Source 
- Unif shows ROM_size and VROM_size in bytes, while codebase expects these to be
in chunks of 16K for prg and 8K for chr. Update Unif to represent size as its
expected to be.

- Change PRGRomSize and CHRRomSize to represent sizes in bytes to make it consistent
with the rest of the size-related variables in struct CartInfo.
