ML-x17 option boards

Option boards can be used to add additional inputs/features to an ML-x17 data logger or to perform signal conditioning. You can mechanically stack up to 3 option boards, but only one board per category ID (CID). Some boards are having a switch to choose a different CID, so you can stack multiple similar boards. Converter(OC) or Power (OP) boards don't have CID's and you can stack as many OC/OP-boards as mechanical feasible. OC-boards don't make use of the internal control bus, but are wired to existing inputs/outputs/ports.
