Todo List

Class daisysp::AdEnv

- Add Cycling

- Implement Curve (its only linear for now).

- Maybe make this an ADsr_ that has AD/AR/Asr_ modes.

Class daisysp::Phasor

Selecting which channels should be initialized/included in the sequence conversion.

Setup a similar start function for an external mux, but that seems outside the scope of this file.

Class daisysp::PitchShifter

- move hash_xs32 and myrand to dsp.h and give appropriate names
