Feature Request: Sorting Artwork by Dimensions

I would like to request a new feature in MP3TAG that would allow a field to sort the dimensions of the artwork.

I know there is already a way to sort based on artwork size but isn't as helpful in my situation where I can have a 3000x3000 artwork that is smaller in size compared to a 500x500. That's why, sorting of dimensions comes in handy and would allow me to replace artworks that are 300x300 and update them.

Please see the release notes for V2.88

[2018-04-09] NEW: added fields %_cover_width% and %_cover_height% for width and height of first embedded cover art. (#41243)
