Virtual odometer

Virtual odometer is used to calculate traveled distance in FMB900 as a separate I/O
element. When FMB900 detects movement, it starts counting distance using GNSS signal: every
second it checks current location and calculates distance between current and previous point. It
keeps adding these intervals until it is time to make a record, then FMB900 records its location
and adds odometer value, which is equal to the sum of all distances, measured every second.
User can choose Odometer mode: 0 – Normal mode, or 1 – Continuous.
At Normal mode, when record is made, odometer resets to zero and distance calculation
starts all over again.
Continuous odometer mode requires ignition (configured Ignition source) to be turned on.
Odometer counts all distance calculations from records and sums them to one distance.
Continuous odometer stops counting, when vehicle is at stop and ignition is turned off.
