cam900 ef104ce0b0 Add VRC6 support
2 Pulse channels:
- 8 level pulse duty cycle, DAC mode(just ignores duty cycle)/pulse wave mode, 4 bit volume.
- Furnace support PCM playback in pulse channels with duty cycle ignore mode.

Sawtooth:
- nothing but 6 bit volume (8 bit accumulator in technically) and 12 bit frequency (periodic).

VRC6 instrument:
- 6 bit Volume macro for finer sawtooth volume handling, also 3 bit Duty cycle macro for pulse channels.

Duty, PCM mode command and Duty macro affects for pulse channel only.

# VRC6 instrument editor
VRC6 instrument editor consists of only three macros:
- [Volume] - volume sequence
- [Arpeggio] - pitch sequencr
- [Duty cycle] - spicifies duty cycle for pulse wave channels
