Fast file upload to SD card using sdwire hardware

plugin uses sdwire hardware to handle fast Upload to SD.

sdwire is a device with micro sd card (inserted into it), micro sd connector (inserted into 3d printer) and a micro USB connector to connect to host (like raspberry pi or other Linux based system).

Inserted sd card can be then made visible to the 3d printer or to the USB host (as regular usb-storage). Copying to sd card from raspberry pi host using sdwire is fast (~10MB/s) compared to 115.2k serial port (~3KB/s; serial port slowness and g-code protocol overhead).
