8 channels overflows the HID interface

[cbteeple]

Due to limitations on the data speed of HID, the max number of channels seems to be 7. Need to implement better HID sending protocol, or switch to Ethernet communication to prevent this bottleneck.

This is fixed in THIS COMMIT where we use only 2 decimal places in the floating point numbers we send back to shorten the message. THIS IS A HACK. It may also not be necessary now that we split up the setpoint and measured data messages.

We should absolutely implement a real message protocol though. Converting everything to strings is a really inefficient way to send data.
