Moved DiveO2 sensor specific funtionality into separated file: Having the protocol functions of all sensors within one file made the code hard to ready and created aa risk of interference between the protocols. In furture every (new) sensor should be maintained in its own source file. The ols UART.c does only contain the function which are used by all UART protocols (common functions).
