[mh] Insteon FanLinc Fan Status Fixed

What was always a curious annoyance turned into a rabbit hole.

I noticed that on my FanLinc's when I would change the fan speed the
command was sent but the object in MH never got updated with the new
setting. Odd I thought but not a big deal.


Well I tried to write some automation around the fan speed changing and
none of the events would fire. This led me down the rabbit hole to discover
the code that deals with the ACK from a FanLinc was built incorrectly and
thus a Fan (Group 02) ACK would never be processed, which means MH would
never update the state of the object and thus no code that watched for it
to change would ever fire.


I fixed it.
