Script Nodes for code based editing

A script node would make video editing to the next level, let it be converting a video to ASCII output (based on it's BW pixel colour) right from blender to complicated math functions of making masks with math.

it could have a node input/output of an 'image' based on a code equivalent of special type of input, like image or video with a 'type function' so it's easy for blender to figure out what type on input/output we are dealing with .

For an example, this script on gitHub let's me make a video to ACII convertor github.com/lavnishhh/Live-image-to-ASCII

but only if it was in blender, it opens a lot of opportunities of letting me color grade video, composite it and have everything done in one application, which is what blender specializes at.

(Also has geometery node implementations)
