feature request: simple #image render / custom additional parsers

reading https://github.com/inkle/ink/issues/336 you suggest to use #image myimage.png tag to let Unity/JS render the image later.

how would it be difficult to render it in Inky editor? just a simple
would be enough

is there some possibility to plug into the renderer aditional custom parsers? (so that i could render #image by myself)

thank you!
