spidriver: Add support for the Excamera Labs SPIDriver programmer

Browse Source 
This is a SPI hardware interface with a display (https://spidriver.com/),
connected as an FT230X USB serial device at a fixed baud rate of 460800.

Firmware: https://github.com/jamesbowman/spidriver
Protocol: https://github.com/jamesbowman/spidriver/blob/master/protocol.md

Most of the implementation is copied from the Bus Pirate programmer.

Tested with a SPIDriver v2 by reading FM25Q128A flash memory on Linux.
