[Suggestion] Chip register view(s)

[aquamarine-axo]

I think that there should be a feature where you can view the registers of the different chips that you have in your song (kinda like 0CC-Famitracker's register view). This would be useful for seeing how your song might affect the different registers in the console/chip's memory, and this would be especially useful once exporting to ROMs becomes a thing.

Implemented for 0.5.7 (kind of).
