- the UART communication is improved based on UART Idle line detection interrupt
- an Rx ring buffer is used to manage the UART incoming data
- both Tx and Rx are efficiently handled using DMA
- added posibility for User commnds via UART in DEBUG mode
- added platformio.ini so firmware can be built using Platformio too

- In case of an Rx error instead of stopping the complete UART, only the Rx DMA is aborted and restarted.
- disabled the Rx errors to avoid DMA stop and additional need to manage the UART error handler
- to completely disable UART init functions in case is not used
