BUG FIX FOR RMT EXCESS TRANSITIONS

Problem
~~~~~~~
Using a UHF receiver throws noise into the RMT peripheral.
Standard IDF function  esp-idf\components\driver\rmt.c reports 
"RMT RX BUFFER FULL" (line 593) when attempting to pull a 
noisy capture.


A core panic occurs when the system is writing to FLASH memory:
  FOTA updates
  SPIFFS updates
  Preferences updates
  
If the RMT interrupt occurs during a flash write a core panic due to 
accessing non cached memory, being the debug message string.

Commenting out the debug message line allows the code to function OK.
System does not crash, but we lose the warning. 
(On the contrary, it is an annoying message anyway).

How to fix it
~~~~~~~~~~~~~
Get the ESP-IDF for the ESP32
Determine the IDF release used by arduino-esp32. This is best achieved
by examining the results from calling the run time esp_get_idf_version().
The first part of the SHA of the release is the value following the "g" 
in the last field:
  eg:  v3.2.3-14-gd3e562907    =>    d3e562907
  
Locate and switch the IDF to that SHA.

Comment out the debug print @ line 593 of esp-idf\components\driver\rmt.c 

Create a copy of the IDF Blink example:
eg:
  esp-idf\examples\get-started\blink ->  
  esp-idf\examples\get-started\arduinobuild
  
IMPORTANT:
Copy the sdkconfig file from the arduino-esp32 build being used to the copy 
created in the previous step:
  eg for platformIO 
  C:\Users\$USER$\.platformio\packages\framework-arduinoespressif32\tools\sdk
  -> esp-idf\examples\get-started\arduinobuild
  
Using an ESP-IDF command prompt, navigate to the project
  eg:  esp-idf\examples\get-started\arduinobuild
  
Execute idf.py fullclean
Execute idf.py build  
  
Copy the libdriver.a file from the build result to the arduino-esp32 lib:
  esp-idf\examples\get-started\arduinobuild\build\driver ->
  C:\Users\$USER$\.platformio\packages\framework-arduinoespressif32\tools\sdk\lib

delete the libFrameworkArduino.a file from the PIO build outputs
  eg .pio\build\esp32dev

Rebuild the PIO project, the Arduino libraries will be relinked, using the new
libdriver.a

Upload and test new build

PROBLEM SOLVED!
