FIX: Explicitly clean up temporary files in HTMLWriter
- HTMLWriter inherits from FileMovieWriter.- FileMovieWriter create a non-context manager TemporayDirectory on init.- The TemporayDirectory is cleaned up in the cleaup method of FileMovieWriter.- However this method (and its call chain through finish) try to either call a subprocess to merge a bunch of single-frame files into a movie (not relevant) or to clean up such a process (not relevant).- The least disruptive fix is to duplicate the file clean up code.
