Add tone() and note() functions #22

I think a tone() function would be nice to have in the next update (4.2.0)

Initial thoughts on how this could work ...

use the existing pin management features of this library
can auto-attach or attach to specified channel
this function to be non-blocking
the frequency and resolution will affect a secondary channel. Therefore, ensure that this secondary channel is still useable for LED fade control (variable duty).
Add an ESP32 example showing use tone, servo and led fade control.
