Added archive.org connector

#Archive.org connector 

Added archive.org connector for their html5 jw6 player.

## Test Cases

Sometimes the player included both track number and artist, presumably from ID3 tags etc which I have attempted to handle.

- Artist, track number, and title: https://archive.org/details/WildSpace
- Artist but missing track number: https://archive.org/details/MutexCollection
- No artist or track number in player: https://archive.org/details/8bp033

Let me know of any suggestions and feedback.
