* Retains ability to read from Analog Pin
* Adds ability to read RSSI from PWM channel value as is done in OpenLRSng, EazyUHF, and various other LRS.
* Handles any type of RSSI that provides RSSI values inverted - i.e. when the low value is the best signal and the high value is the worst signal.
* Has different key names from all existing RSSI parameters to provide for a clean break and easier distinguishing.
* Existing parameters are marked as obsolete
When the rover goes into guided mode it sets the current location as
the guided point to goto. If the rover is stationary when this
happens no problem. If however the rover is still rolling (say going
from AUTO to GUIDED) then the rover would go past its guided position
and get confused and begin to circle it. This change resolves that issue.
As the previous commit as doubled the number of reads required to
confirm that the mode change switch has been changed this means it
will halve the speed it changes at. So we double the rate at which we
read it to keep things consistent.
