[BUGFIX] Ensure StaticRangeMapper applies zero prefix to internal map

StateRangeMapper routing aspects defined like the following did not use
leading zero (0) prefixes due to internal number conversion to integer:

    month:
      type: StaticRangeMapper
      start: '01'
      end: '12'

Zero prefixes are applied in case they were explicitly given in either
start or end property for StaticRangeMapper settings.
