adccmds: Add support for min/max temperature check filtering
Extend the ADC out of range check so that it is possible to sample
multiple times before going into a shutdown state. This reduces the
chance that measurement noise will cause an error. In an actual over
temperature (or under temperature event) it is expected that the
sensor will consistently report the problem, so extra checks for an
additional second or two should not substantially increase risk.
