* upgrade to IDF v5.1.1
* add new synchronization implementation, use sample stuffing / removal to keep up sync
* use big DMA buffer for I2S and improve sync
* Add DAC TAS5805M as custom board
* add wifi credential reset
  o press reset button (nRESET pin) 3 times
    but wait about 1s between button presses
    the button press counter is reset 5s after boot
* Add support for PT8211 DAC (#78)
