[PD] Pd to Raspberry Pi SPI

[Martin Peach]

It might be better to extend [comport] to handle SPI devices.
Assuming you have a /dev/spidev* already existing (I just spent a couple 
of days getting that far on a Beaglebone Black), the rest of it is quite 
similar to ordinary asynchronous serial communications.
