added method for restarting the phase accumulator #475

Added a method restart() to AudioSynthWaveform and AudioSynthWaveformModulated to reset the phase_accumulator to 0. This allows the phase of multiple oscillators in a synthesizer to be synchronized upon note on.

I am completely butting my nose in here...but I support the idea that this is a worthy functionality to include. Oscillator reset is absolutely a thing. It's not super-common, but those synths that do it are very distinctive and iconic. Moog Taurus bass pedals being probably the most iconic.

So, yeah, I have not tried this particular implementation, but the motivation is good. It's a worthy functionality for an oscillator to have.

This is an absolutely necessary function, for example to start modulating the frequency or amplitude with an LFO with a fixed phase angle at every "note on".

I've been using it for years.
