Feature request: Would it be possibly to add ikari_01's findings for the CX4 chip to add support for Hirom with 32MB

Cx4 notes by ikari_01
I'm not sure if the work to add this would be worth it but it would definitely be interesting thing to add since the CX4 chip does support this.

I looked at the source code for higan and bsnes v115 and it looks like byuu already added the 32mb hirom for the cx4 chip. If someone is willing to add the 32mb hirom to bsnes plus so I can trace the code then I would be able to convert mmx2 and mmx3 to hirom.
