Changelog:
- nall: converted range, iterator, vector to 64-bit
- added (very poor) ColecoVision emulation (including Coleco Adam
expansion)
- added MSX skeleton
- added Neo Geo Pocket skeleton
- moved audio,video,resource folders into emulator folder
- SFC heuristics: BS-X Town cart is "ZBSJ" [hex_usr]
The nall change is for future work on things like BPA: I need to be able
to handle files larger than 4GB. It is extremely possible that there are
still some truncations to 32-bit lurking around, and even more
disastrously, possibly some -1s lurking that won't sign-extend to
`(uint64_t)0-1`. There's a lot more classes left to do: `string`,
`array_view`, `array_span`, etc.
