Baudrate increased

[!IMPORTANT] To support the ESPRi project with release version 21.4, the baudrate within the NUNU-firmware is changed from 38400 to 115200.

Therefore you cannot use default CPS or Chirp. To be able to communicate to UVK5 with NUNU-firmware the already dedicated Chip .py-driver is changed to a special version with 'BAUD_RATE = 115200'.

Select the file uvk5_egzumer_115200_baud.py as argument, which is not mentioned in the READ.ME. See READ.ME and be aware to CHANGE THE ARGUMENT TO THE FILE uvk5_egzumer_115200_baud.py.

P.s. The increased baudrate has no impact on flashing the radio.
