Episodes and Shows functionality

[danluki]

Partly resolved #36 I implemented episodes and shows Spotify API functions, they are pretty much the same as album + tracks. So, the code is very close to them.

The steps I did:

1. Saw how you implemented the same logic inside album and tracks.
2. Created types for episode and track, which is close to album and tracks.
3. Created new functions, that implements logic from episodes and tracks chapters of Spotify Docs.
4. Also, I tested it a bit by hands and it seems to work good.
5. Wrote some docs for new functionality.
6. Run pnpm lint and default tests.

Thank you so much for your contribution to the project! It looks like good quality code to me. In the future I would like to write tests for this and other functionality, but so far everything looks good. In the near future I will also try to make the contributors section in the readme. Thank's again!
