I'd like to propose modifying the WrenchSensor class to deal with
# jr3 driver under LXRT (existing)
# jr3 driver under gnulinux
# non-jr3 under gnulinux
# mockup sensor with no underlying driver (ie used for unit tests or simulation)

All of this can fairly easily be dealt with by either inheritance or application of adaptors or other methods undoubtedly.

Any maintainers out there interested in this?
