as of now the SSG part of these chips is handled by a DivPlatformAY8910
within the DivPlatformYM2610.
this means less code duplication and therefore prepares for
OPN/OPNA support.
its 16 channel wavetable/PCM chip, with (optional) stereo support.
Its also has envelope, this feature has similar as AY PSG's one but its shape is also stored at RAM, and each nibble in envelope data is for each output: so i decided to added some feature for more stereo-ish envelope.
Split: Envelope shape will be splitted to Left and Right half for each output.
HInv, Vinv: Envelope shape will be Horizontally/Vertically mirrored the left one.
Max sample length is sample bank size of Seta 2 arcade hardware (currently not emulated yet, nor it doesn't support on VGM).
Chip id is temporary, it can be changed with to suggestions.
