RLS Orbis SPI support

Hot on the heels of BiSS-C encoder support intended for high end applications, I am excited to announce that moteus now supports the RLS Orbis SPI protocol for lower-end systems as of firmware version 1.0.0.

The RLS Orbis is an absolute magnetic encoder suited for use with diametric ring magnets and can be configured to use a number of different communication protocols. If you have a moteus-n1 or moteus-x1, then the newly released BiSS-C support already lets you communicate with them. However that left out the moteus-c1, which does provide the 5V necessary for an Orbis to function, but does not have a built-in RS422 transceiver.
