Add ability to call Arduino tone and noTone functions. For non-Arduino architectures,
similar functions to tone and noTone would need to be implemented.
The duration could be extended if necessary. Duration could also be optional. If left out, the user would need to send the NO_TONE command to stop the tone.
An implementation of this proposal is currently available here.
// wrapper for tone function
0 START_SYSEX (0xF0)
1 TONE_DATA (0x5F)
2 TONE (0x00)
3 pinNumber
4 frequency LSB (in HZ)
5 frequency MSB (in HZ) (audible range is 20 HZ to 15,000 HZ so 14 bits is sufficient)
6 duration bits 0-6 (in ms)
7 duration bits 7-14 (in ms) (max duration is 16,383 milliseconds)
