Support viewing Twitter collections 
[TweetDeck](https://help.twitter.com/en/using-twitter/how-to-use-tweetdeck) and other clients can create public groups of hand-selected tweets called collections using the [v1.1 collections API endpoints](https://developer.twitter.com/en/docs/twitter-api/v1/tweets/curate-a-collection/overview). There are also endpoints for [listing collections](https://developer.twitter.com/en/docs/twitter-api/v1/tweets/curate-a-collection/api-reference/get-collections-list), [retrieving information about one](https://developer.twitter.com/en/docs/twitter-api/v1/tweets/curate-a-collection/api-reference/get-collections-show), and [retrieving the collected tweets](https://developer.twitter.com/en/docs/twitter-api/v1/tweets/curate-a-collection/api-reference/get-collections-entries).

Unfortunately, it doesn't seem Nitter can discover them given a URL like https://twitter.com/markjgardner/timelines/1606000784457564161
