Merge branch 'master' of https://github.com/nstanger/process_podcast

• Added Visual Studio Code workspace.

• Added --copy-audio and --copy-video options to disable all additional stream processing (reducing audio channels, etc.). ...

• Removed -n for --no-normalise.
• Added configurable audio and video codecs via --audio-codec and --video-codec options.
• Fixed bug where the final punch out time for an odd number of timestamps was incorrectly calculated.

• Added --no-normalise option to disable normalisation of the source audio.

• Rewrote shellquote() to ignore things like command-line switched and executable paths. Also only execute the catch-all regex when no other regexes match (closes #27). ...

• Switched to double-quoting of strings because that makes it easier to handle single quotes in strings (which is more likely than double quotes).
• Added more test cases.

• Updated regular expressions in ShellCommand.shellquote() to catch the weirder edge cases (closes #26).
