New feature: Partial sequence deletion in Mapillary web frontend - within time-range

Start by comparing this proposal with related issue #638 and reviewing how the Mapillary web frontend currently deletes individual images or whole sequences. Define the supported before, after, and both-time-range behaviors, including the default interval, and consider how completion would be verified without deleting images that should be retained.

Background

• As an contributor, I typically try to upload Ricoh Theta X videos.
• After data ingestion, I typically inspect the imagery in the Mapillary web frontend.
• When a complete video is uploaded it can happen that part of the sequence has bad GPS information, thus I would like to delete the images that have a faulty position, (alternatively reinterpret & interpolate the GPS data without the faulty GPS positions and trim/delete any unnecessary images that do not meet the minimum distance rule).
  • Severe examples have been found, where a single GPS glitch have spread 30+ images over more than a single continent, when normally only 1~3 images would normally have been retained if the actual positions ware used instead of the faulty interpolated positions - (e.g spread from the US all the way to the Indian Ocean).
  • However in some cases the the fault can be so small that it is a quick review before a upload is unlikely to not catch the fault, e.g 10~100m off, and then the fault need to be addressed retroactively when found.
• In such cases the web frontend offers to delete individual images which can be a tedious procedure, it has also been unreliable requirening the procedure to be redone multiple times - making it even more tedious. Deleting the whole sequence is available today. Would be better if the web-GUI allowed deleting (alt interpolating) images for a specified time before, after or both; defaulting to 1 second before+after (i.e. deleting the images typically affected by signe bad GPS position - after interpolation of positions).
• but would also drop the portions of the sequence that should be retained.

New feature proposal

• The Mapillary webfront-end should provide an option to delete all images within a specified time (before, after or before&after the currently selected image.
