[2023.7.2] Add filter for files containing GPS in filter panel

[Rene Toepfer]

When I started IM I have created a filter at Filter-Panel which shows all files containg GPS data. By accident I have deleted this filter and I wanted to re-create it.
Believe if or not, I do not find a setting which filters by files which contain GPS data. Unfortunatelly, [1] refers only to filter by a specific location but not generally to GPS.

1. A simple metadata Value filter for Latitude does this.

2. Or, the IMatch Workflow Categories|No GPS Data category contains all files without GPS data.
It uses the formula "@MetadataTag[gpslatitude,novalue,rawvalue]" for that purpose. Use hasvalue instead of novalue to create a category that contains all files with GPS data.

See hasvalue and novalue for more info.
