Extended tx20.ino for supporting Technoline WS2300-15 Anemometer.
This Model is very similar to TX20 - but use a slightly different Datagram.
use it with #ifdef USE_WS2300_WIND_SENSOR -> choose only one of them (TX20 || TX23 || WS2300-15)
Usage is the same as TX20/23, values are proofed with original Weather Station from Technoline.
Sorry for my Code.. was try and error some hours to get it working with the #ifdef stuff..
Documentation Update follows soon..
new JSON for TX2x (for legacy format define USE_TX2x_LEGACY_JSON)
exp weighted average prevents jump in avg values after period
refactor sensor reading
