No way to set sprites to blank/empty?

[Meorge]

I wanted to do an effect where the camera pans through the courtroom but the characters are absent; however, it appears the sprite command doesn't have a way to make a given sprite position be blank. We can show/hide the witness stand and benches via the hide command, but not just the characters.

This should be an easy fix, I think - just need to add a hardcoded option to the handling of the sprite command in ace_attorney_scene.py around line 676.
