Northern Man 19d58e01e0 Defensive code for Heltec Display (#1296) 
Added to Heltec board display code logic to reduce corruption of messages on the display

Two piece of defensive code were added

- Only display messages to the display when operating on Core 1 ( Default Arduino ESP32 CONFIG_ARDUINO_RUNNING_CORE )

- Only display one character/string at a time

In the event of failure, default to Serial output.

PS SSD1306 driver similar issues

Northern Man 8bc65d62dc Update of rtl_433_ESP to version 0.1.3 - Support for SX127X transceiver module (#1291) 
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

1 - Set default LCD log level to WARNING
2 - Implemented a macro based displayPrint function that will be usable across different displays

- Added logo display when idle
- Fixed log-lcd mqtt function
- Enable OLED Display on Heltec Boards
