OBS Python OBS Recording Demuxer 1.0.1

* Fixed a bug where the script would error out if you didn't wait for ffmpeg to close before starting a new recording
* Fixed a unintended side effect where the "delete source file" code didn't check the return code of ffmpeg (we only want to delete the source file if the demux action was successful)
* Added extracting the video metadata to the output directory in the metadata.ini file
