Use the same functions and structs as the other DMM protocol parsers in hardware/common/dmm. Among other things, this allows the functions to be used from drivers in a generic way, e.g. in serial-dmm, uni-t-dmm, and possibly other drivers.
This is not yet fully finished, but works for most use-cases. Tested with a UNI-T UT61D using the UT-D04 USB/HID cable (new version).
