We don't ship SVGs here anymore, so let's remove that README. And instead add
one to the devices directory.

This directory contains the data files for each supported device. libratbag
reads these files to identify the backend driver for any given device. If a
device is not listed, libratbag will not support it.
See the device.example file for instructions on the various options.
