Gets an MP3 file ready to post for the Polytechnicast using eyeD3 to set all the MP3 metadata plus artwork.

Accepts a file path as a parameter,
assumes that the show notes and podcast MP3 file are named the same,
except for their given file extension,
and are in the same file directory.

Script is based on examples in the eyed3 documentation,
combined with this blog article which shows how to embed an image:
