LoRaWAN MAC Battery Level reporting

[bmarkus]

There is a lora.set_battery_level(level) method introduced in latest firmware:

Unfortunately current implementation is not in line with LoraWAN Specification v1.0.2

Method is passing values between 0 and 100 to the LoRaWAN server directly which means on server side 39% for level=100, 20% for level=50, there are no way to report battery level 40-100%.

Default value is 0 which indicates device is running on external source, level=0 doesn't mean 0%. Proper default value would be 255 which by the way can't be reported via this method.

I advice to allow level=0...255 and use level=255 as default, adding the quoted text from the LoRaWAN specification to the documentation.
