Added protocol functions for UART DiveO2 sensor:
The code has been modified to support the handling of several protocols (including baud rate changes). The data is requested by polling and passed via DMA into a ringbuffer which is then parsed by a cyclic function call in the main loop. At the moment only the O2 values are forwarded but because the sensor send several types of data within a signle message already more is extracted but yet discarded.
