Enable creating LUTs from strip textures within Resonite

[Dusty-Sprinkles]

Is your feature request related to a problem? Please describe.

Currently if you use one of the common methods of making a LUT outside of Resonite within the game by using a camera (creating a packed strip of 32 squares (up to 32x32 by importer restrictions) you cannot turn that into a static texture 3D without exporting the resulting texture and re-importing the file

Describe the solution you'd like

The ability to copy and paste an image from within resonite as a LUT

Describe alternatives you've considered

Exporting the image as a png and then re-importing it, which is very tedious compared to just being able to do it all in resonite

Additional Context

This could be fixed in such a way that #2946 is also fixed (allowing images to be directly read as LUTs from the clipboard) or maybe by copying texture exportables as the image file itself like what firefox seems to do
