Kickr: Load setting fixup

Fixed up the Kickr code to resend the load if the
user is generating more than 50% over the load or
is only generating 50% of the load.

This is in case the last message was not processed
for some reason (connection being established, or
noise).
Kickr load setting fixups

The load setting was not working properly, this update
ensures the load is set 10 times a second, but will
generate errors even though the device claims to be
connected.

Also added a few new methods to get/singal connection
status in the code.

afterwards.
