Migrated CO2 protocol implementation to new format:
The previous implementation was a monolithic protocol implementation which was not usable together with the multiplexer. The new implementation moves the CO2 implementation into a separate C file and decoubles the upper layer external interface, which is not able to handle DiveO2 and CO2 sensors in parallel without restriction to port assignments.
