Allow us to import a list of accounts we already follow

[thibaultmol]

I personally follow a lot of accounts, and now that i have the extension installed I often see that it detected new accounts, but they're ones I already follow.

So being able to export the following list from mastodon and import into the extension would be nice to prevent this 'already know this person' problem

It would be nice if I can point it to my profile(s) and it would pull the follows automatically.
