Create an Internal ID for Podcasts #40
Description
To make it easier to add other features like downloading specific podcasts, it would be a good idea to add an ID attribute for podcast records. Using a straight numeric ID would not be ideal as there may be cases where the numbers to get out of sync.
To create a safe unique identifier, you can create a short hash of the podcast audio URL as follows:
import hashlib
feed_url="https://media.transistor.fm/9c4b292f/754f684f.mp3"
feed_id=hashlib.shake_256(feed_url.encode()).hexdigest(5)
This will create a short 10 character hash that would be unique for every feed regardless of the changes to the feeds. As long as the feed does not re-use podcast URLs, there should be no collisions.
This ID should be stored in the feed.json as id and it can be used to download specific podcasts.
