Allow image objects to support custom properties (especially Date) and auto-extract EXIF metadata

Images should have the same properties customization as other objects, especially allowing for a date property.

If you are uploading images en masse, Capacities should be able to detect that metadata and automatically fill that date property.

This is a huge missed opportunity (and I'm surprised it's not added yet, with how powerful the rest of Capacities is). Now If I want to link all my photos to dates I have to add the dates to them manually.

I think it would be a great idea to have the date available automatically, then the user can decide whether they want to link the date to the respective daily note. If not adding this auto-date feature to image objects by default, at least allowing for the customization of image objects would fix this.
