Adding USB relay support

[khobar]

I was highly hopeful of enabling bulb mode on my D5100 via USB relay board, and the first one I bought was HID which does not assign a COM port (I was not aware such a beast existed, now I do). So I bought a different USB relay that is assigned COM5, but it's not KMTronic - it's SMAKN LCUS-1 (http://www.icstation.com/lcus-relay-module-ch340-intelligent-control-switch-relay-module-smart-home-p-12488.html). I have tested it manually with my Nikon D5100 using the KMTronic test app, and it works, but the relay ON and OFF commands are different i.e. instead of FF 01 01 for on and FF 01 00 for off, it's A0 01 01 A2 for on and A0 01 00 A1 for off.

Am I overlooking something (like a config file)? If not, any chance support could be added? 

Thanks!

I just added support for both KMTronic ASCII and HEX cable.  I was able to test both these cables since KMTronic was kind enough to send me complimentary cables for testing.

I also added support for the SMAKN LCUS-1 cable mentioned above but I'm not able to test since I don't have this cable.  I simple took the command posted above as-is.  I hope it will work.

This will be in the next RC release.  I'm not able to post it now because I have a few breaking changes in progress and I need to complete these before posting the RC release.

Thank you.
