src/Plugin/Field/FieldWidget/GeofieldDmsWidget.phpGeofieldDmsWidget & src/Element/GeofieldDms enhancements and fixes:
- Generate a valid Geofield only if the DMS coordinates are valid, otherwise delete the entry.
- Generate a default entry that is empty and not 0, 0 , 0 (that would create a new geofield on every save)
(Issue #2142071 by holist, itamair: Allowing coordinate entry in degrees-minutes-seconds DMS format)
Issue #1840894: Add documentation on how to save a Geofield programatically.
