Feature Request: Parameter phase: for synth :sine

[zenon]

I'd like to get a parameter phase: for the synth :sine, so I can say the below to get various Lissajous figures like https://en.wikipedia.org/wiki/File:Lissajous_phase.svg
That would be awesome.

# Left
synth :sine, attack: 0, sustain: 15, release: 0, pan: -1, note: :c3
# Right
synth :sine, attack: 0, sustain: 15, release: 0, pan:  1, note: :c3, phase: 1.57

If this was an opt called phase: with a value between 0 and 1 would that work for you?

Would make me happy, yes!
