Supports "dmenu" chooser type, which is called with a dmenu type list piped to stdin, "simple" type, which recieves nothing on stdin and default, which tries the hardcoded choosers. Choosers are required to return the name of the choosen output as given by the xdg-output protocol. Thanks to piater for closing overlooked pipes. Thanks to ericonr for suggestions regarding fork and pipes.
