[Feature] Improve the Scene Duplicate Checker,

[alucicrazy]

Is your feature request related to a problem? Please describe.
I have some duplicated scenes because a new one was created from a different video file, and i want to merge both while keeping the stats of the oldest "created at", they have been identified and both have the same Stash ID

Describe the solution you'd like
A way to merge all the scenes with the same Stash IDs keeping the info of the oldest "created at"

Describe alternatives you've considered
This could be implemented on the Scene Duplicate Checker, with 2 new options, one is a new select option "Select the Oldest Created At Scene" and the other would be a option to "Merge into Selected" since currently the merging can only be done group by group
