Move the image in ImageView component to canvas

[twsl]

I'd like to propose the move of the actual image from an image tag to the canvas, mainly because it would make my feature request https://github.com/heartexlabs/label-studio/issues/1425 much easier to implement using the existing filters in konva.

While this might come at a minor performance penalty, I do think the advantage of interactive filters to support labeling justifies this move.

Any help implementing this is appreciated as I am currently having problems calculating the size of the image.

Messed up the git history due to a typo in the email address. New PR will include filters already and not move the image to the canvas, but allow to display it in addition for filters.
