Adds an OD sensor implementation which corresponds to that on the default evolver box. For now the calibration is left out but this shows clearly where it would fit: in providing a value for "density" field of "Output".
Adding also some shared infrastructure for testing these serial-based devices. Probably more of the test infra could be shared for hardware modules, but leaving it specific to OD here.
