Due to these problems
* possible race condition, two events competing
* pattern detection work a little different for different IDF versions
* switching between pattern detection and data reading is complicated
* using just data events is easier for porting to a different communication peripheral
These changes were made:
* Removed the UART pattern detection entirely
* Used manual pattern detection after reading plain data from the UART
