Add Nord Electro 5 config file

Add a config file containing the CC mappings which are compatible with
setBfree's existing control functions. Some features do not map
precisely to how setBfree interprets the control codes, for example the
Rotary controls - support for this will be implemented in a subsequent
commit.
