Enhanced scan stats, including number of "active" accounts

[cbirdsong]

It would be interesting if Fedifinder showed prominent stats on the number of Twitter accounts you follow with a detected fediverse handle as a percentage, like "32% of your follows are on the fediverse". However, I know I follow a lot of dormant accounts that would skew this data. To really be representative of how much of your network has migrated, it would need to do some kind of heuristic to determine if the account is active on Twitter before using it in these stats?

Here's a quick codepen mockup: https://codepen.io/cbirdsong/full/PoBwZWE

(Having written this up, I now realize this is two separate ideas – let me know if I should make a new issue for one or the other)
