Feature request: Image input from clipboard

Is your feature request related to a problem? Please describe.
N/A - QoL only

Describe the solution you'd like
I would like to be able to take a screenshot directly to my clipboard (Cmd + Ctrl +Shift + 4 / Win + Shift + S) then paste it directly into CyberChef. This is particularly for Parsing QR codes or OCR.

Describe alternatives you've considered
The current workflow requires saving a screenshot to disk, then using the Open File dialog to load the image. This causes clutter as the temporary files must be store to disk.
