Improve Taito Zoom ZSG-2 sound emulation (#3847)
* Improve Taito Zoom ZSG-2 sound emulation
zsg2.cpp: implement emphasis filter, this is a noise reduction scheme
that amplifies higher frequncies to reduce quantization noise.
zsg2.cpp: Add sample interpolation and another adjustable lowpass
filter. This seems to be roughly what real hardware does...
zsg2.cpp: Improve panning registers and identify DSP output gain
registers.
* zsg2: minor changes [nw]
zsg2: Register 0b appears to be status flags [nw]
zsg2: Linear ramping probably makes more sense [nw]
* zsg2: slight adjustment of emphasis filter [nw]
* zsg2: slight adjustment of emphasis filter #2 [nw]
* zsg2: more sober ramping algorithm [nw]
