feat: use consistent file name in gradio (#1932)

* feat: use consistent file name in gradio

returns and uses filepaths instead of numpy image by saving to temp dir
uses double the temp dir file storage on disk as it saves to temp dir and gradio temp dir when displaying the image, but reuses logged output image

* feat: delete temp images after yielding to gradio

* feat: use args temp path if given

* chore: code cleanup, remove redundant if statement
