wikimedia photos: update results filter according to coverage layer

Additionally filter out
- images with non-earth coordinates
- images with both coordinates having less then 2 digits
  after decimal point (remove NASA photos)
- images with either coordinate equal to 0
- images with equal lat and lon
- images whose filename contains "View of Earth" (remove NASA photos)
