Original GitHub issue: https://github.com/ramsayleung/rspotify/issues/421

Describe the bug
Requesting tracks_features for a track that doesn't have features returns null, which serde_json doesn't expect.

To Reproduce
Steps to reproduce the behavior:

Request tracks_features for a track that doesn't have features (e.g. spotify:track:6z99LwRS28wga9xc2u09Po)
Note that serde_json says "unexpected null"

Expected behavior
A track which doesn't have features should be filtered out in the response.

Log/Output data

error=json parse error: invalid type: null, expected struct AudioFeatures at line 1522 column 9
Error:
   0: json parse error: invalid type: null, expected struct AudioFeatures at line 1522 column 9
   1: invalid type: null, expected struct AudioFeatures at line 1522 column 9

Additional context
