Edward O'Callaghan	2141250162	raiden_debug_spi.c: Implement retry mechanism ... This overcomes a problem with the ServoMicro where USB packets can be ack'd by the device without triggering interrupts or loading data into the USB endpoints. The retry mechanism attempts the USB read 3 times before reattempting the write call to avoid performing multiple SPI transfers due to a USB problem. This process repeats 3 times before we return the last error code. Intermediary problems are reported in the status code.

Edward O'Callaghan	e8c0ee7c7e	raiden_debug_spi.c: Clean up RW ops into sep paths ... - The USB SPI interface has been split up into write and read stages. - The packet packing has been transitioned from array based to a struct.
