Fixes #121 Supersedes #185 Redo the PIO program to allow the tone generator on a pin to be updated without interruption, at waveform boundaries. This allows for things like sirens or slurs to be implemented simply. Use an alarm, not the PIO hardware, to manage time-limited tones(). Add a simple siren example.
