Manage prefix on CAN and OBD2 prefix. Searching signals
is made on generic_name (without prefix) and returned vector of string is filled with name with prefix. Then you can process on them based upon their name differently. OBD2 signals will generated recurring request on diagnostic manager and decoding will not be handled the same way too.
