Feature Request: look up twitter follows without submitting twitter account

[stephen304]

It would be great if it was possible to upload the following.js from a twitter account export and find users that way - instead of requiring people to publish an association between their twitter and mastodon accounts.

This would be good for people who use twitter anonymously.

For example, the following.js export looks like this:

window.YTD.following.part0 = [
  {
    "following" : {
      "accountId" : "1111111111111111111",
      "userLink" : "https://twitter.com/intent/user?user_id=1111111111111111111"
    }
  }
]

If I could just upload this and then get the mastodon csv, that would be great.
