Recheck periodically for better quality videos

This being an archiving project, downloading the best quality desired by the Format Scheme is presumably desired. If a user wants 4k but only 2k is available, 2k is what will be downloaded.

Sometimes however the 4k transcode can be delayed and not available for some time. In certain cases it is possible for this to take even weeks

It would be good to emulate what TheFrenchGhosty is doing where you immediately download what ever the best quality is right as soon as it is available. Then periodically check for higher quality videos to be available. This periodic check only happens for videos that are younger than the cut-off period in order to not waste time checking videos that are too old. This period should be configurable by the user.
