Remove EXIF metadata from pictures

[pamoreno]

I think EXIF metadata removal would be a great security and privacy enhancement. I even consider useful something to check which metadata remove, for example, some may want to remove GNSS data, some would like to send that without device info or date, or leave only date, or nothing, or everything, etc.

This can be a useful feature to have, thanks for suggesting! A preference in the privacy section would be good.
