[Feature Request] rotate images in "image menu"

[ruru4143]

Issue

Sometimes you want to scan a page horizontally, sometimes vertically, maybe even sometimes upside down.
For example if you have a long equation and it's cleaner to write it on A4 horizontal, but the next page is vertical again.

My current workflow for that is to upload it to my computer, seperate the images with pdftk, rotate the image and repack it into a pdf again. this is not a good one.

Expected behaviour

If you select an image there should be a rotate button on the top to rotate it 90°

Would you like to work on the issue?

I don't know any Kotlin or Java, but i would tip 10€ to the person who implements it.
