Add SN76489 (or another PSG) chip to support true square voices #6

This simple PSG chip that also was presented on Sega Megadrive game console also was used in game music as YM2612 processes sine-wave only voices and also having of SN76489 gives extra three voices and one noise channel!

SN76489 chips can be used to make existing voices sound better.

As OPNA chip support with embedded PSG upcoming, let's put this or another PSG emulator to use with OPN2 out of OPNA.

MAME has a good SN76489A emulation core that's not ridiculously outdated - https://github.com/mamedev/mame/blob/master/src/devices/sound/sn76496.cpp so it would be useful as an OPN2 companion.

Doesn't the OPNA come with the YMF2149 in one bank?
