In the Adafruit_SPIDevice class, when running on the SAMD architecture in the hardware SPI case, use the SPIClass::transfer(txbuf, rxbuf, count, block) method when writing instead of looping over individual bytes.
...
This makes use of DMA and is noticeably faster.

The SPI.cpp that the STM32 project uses does not have a transfer method with both a buffer and a length. Changes to this file uses a transfer method that just needs a single 8 bit character.
