LSN50 decoder breaks when temperature is negative #32

Closed thomasphorton closed 2 years ago

I wrote the decoder, so this is my fault :)

The LSN50 temperature sensor decoder has an overflow when the temperature is negative, and reports temperatures of 6550+ degrees celcius.

Working on a fix, and also checking other decoders to see if they have similar issues.

i've found some logic in the LLMS01 decoder that i'm going to test out here: https://www.dragino.com/downloads/downloads/LoRa_End_Node/LLMS01/Decoder/LLMS01_Datacake_Decode_V1.0.0.js
