Re: [pwg] audiobooks tf minutes

Based on today's discussions, I've slightly tweaked the example based on
WP:
https://github.com/w3c/wpub/blob/da066cb4ebba3627bdc106022dea435aea7a8b4a/experiments/audiobook/flatland.json

I have my following action items in my list:

   - create the table of contents example
   - port my current prototype player
   <https://hadriengardeur.github.io/audiobook-manifest/examples/player/>
   to the WP variant, use it as the entry page for that example
