Add maidenhead precision logic to Position #89
Description
Description
Position class currently does not have an automatic encoding of gridsquare to be the correct specificity. This can be a problem if a 4-char gridsquare is decoded and then attempted to encode later. This would add additional precision (which may not be very accurate) to the location.
Another example is decoding from a lat/long coordinate with ambiguity.
Consider using the ambiguity value in encodes and decodes.
Acceptance Criteria
- Maidenhead gridsquare decode and encode results in the same precision of gridsquare
- Maidenhead encode does not result in a more precise location than geocoord with ambiguity
