Rtl_433: Norgo NGE101 device support

[martinkaltoft]

It would be nice if someone would look into adding device support for the 'Norgo NGE101 Energy Meter'

The hard work of analyzing and decoding the protocol have been done here:

I simply lack the ability to make this info into a working decoder.

Thanks to protocol description by Jesper Hansen, I was able to implement NGE101 decoder for rtl_433. I have been using it for some time now and it is working very well. Unfortunately I do not have time to finalize it for releasing right now, but hope I can find some time to do that in near future.

That sounds great jamaron, I hope you find the time to make it public.

Just dump the code here and I'll clean that up and integrate it.
Otherwise if somebody wants to go through those blog posts and do a short writeup I might write a decoder.

Please find attached norgo.c and a photo of the device. Pulse width parameters may still need some fine tuning.

The code already pretty much looked good, and works. PR in #1042, needs a bit more clean up. Closing this in favor of the PR.
