remove and detect duplicates from database

[cmosig]

• needs new route for deletion based on ID, to clean up existing duplicates or new uploads.
• new process that autodetects duplicates after upload, after bbox has been created and before everything else (after is_ortho_done and ìs_upload_done). To detect duplicates, compare acquisition year, month, day and check if bbox intersect. If so, flag, and stop processing -> needs to be audited.
• audit page, where two IDs are shown and someone can decide is "duplicate and delete" or "no duplicate, keep procesing". Simplest thing might be to have to frames where each shows the orthophoto and the metadata, i.e. split screen with two times the dataset page. And a button to decide the datasets fate.

Could notify user on upload page and point user to the existing dataset.
