Add support for WEC-2103 temperature/humidity sensor

[tthurnreiter]

This temperature/humidity transmitter came with a cheap weather station.

The only available information on it that I could find is here: https://fcc.report/FCC-ID/WEC-2103

Looks good, thanks! Isn't it more likely that a checksum would be in the last bits at the end? Do you have som example raw codes?

[tthurnreiter]

The checksum is just speculation, I wrote this a year ago, so the details are a bit hazy. There's also an unknown byte at the end, but IIRC that one is constant across different messages.
