The main features of the upgrade to 0.1.3 of rtl_433_ESP are
1 - Change Transceiver Library to RadioLib
2 - Add support for SX127X transceiver module ( I used the 433 Mhz version of this Heltec module for development ).
3 - Added automatic calibration of the RSSI Signal detection Threshold
4 - Removed dependency on loop for start and end of signal detection, and moved to a ESP32 Task
5 - Moved received signal decoding to a ESP32 Task
6 - Identified Blueline PowerCost Monitor decoder as source of significant memory overhead and disabled.
7 - Multi Receiver support has been validated with RF, RF2 and PiLight
