Delay write exif keywords

[ronbruins]

It would be nice to have the option to queue the writes of exif data back to the files. Now when assigning keywords to a large number of files start exif tool to do the job, and having a performance impact. Would it be possible to queue them and then start the actual update of the files when the job is started? This way a workflow can be finished and then the system can do the writing eg. overnight.

I already do this a bit (if you've read the technical readme you'll see details of how I conflate exif operations to minimise writes to the image files.

It would be pretty easy to add a delay so that exif writes were done after, say, 4 hours.

I could also put in a "work period" so that AI processing and exif writes were done between certain hours (eg 2am - 5am etc). The indexing and metadata scanning would always want to run immediately though so you get new images appearing as soon as they're added.
