Di2 Nexus-5 hub and Shimano EP8 motor unit unsupported

[pierrebrt]

I'm the happy owner of an Omnium E-Mini-Max with a di2 Nexus-3 and a Steps EP8 and I found it was supported by ki2. First, the speeds of the hub weren't displayed, also I wonder if the cadence sensor of the motor unit and probably its internal power sensors could be supported. I think it would be dope.
