[FEAT] Enter compare mode automatically + compare multiple pictures

[TheBestPessimist]

Is your feature request related to a problem? Please describe.
I would like to enter compare mode by pressing shift + left or shift + right, to compare current picture with previous or next respectively, instead of pressing c.

Additional context
I would like to be able to compare multiple pictures at once, similar to how zoner studio does it. See the following video. Ignore the filmstrip, i used it to show how it deals with multiple selection

Thanks for the feedback! I will add these two shortcuts.

However, supporting comparisons for more than two pictures might make QuickView quite bloated and heavy, though I'll still look into it and see what can be done.
