Looks good. @FokkeZB please test

[FokkeZB]

@johanstokking I will once I get my/an Uno joining again.

Rebased on master, updated API.md (included private configureChannels) and tested both with only region and with custom sf and fsb. The only difference in what the debug logs show is the data rate. Which is 4 for the default and 5 when I use sf = 8, fsb = 3.

@johanstokking I documented the min/max sf I found in the LoRa docs. Do we have information for the min/max fsb as well?

[n2jn]

@FokkeZB I couldn't find any document either with the min/max of fsb but I did some tests with the US915 frequency plan: I noticed that fsb activates 8 channels in a row starting by the beginning (for example for fsb = 1 it activates channels 0 to 7, for fsb = 2 channels 8 to 15, etc ...). So to be able to activate whatever channel we want it would be logical to put a maximum of 9 to fsb and a minimum of 1.

Good to merge @johanstokking
