Implement the get following/get followers methods on the account object

[Riduidel]

According to mastodon API, it's reasonably easy to get the following/followers accounts.

Could we have the equivalent methods on the account object of your API (maybe with some caching, but I don't know)

I'm starting a PR.

Would you prefer to have $client->getFollowedBy($account) or $account->getFollowedBy(). The second would seem more object-oriented, but would require the account to contain a reference to the client.

For the sake of simplicity, I think I'll go the first version. What do you think ?

This project is basically dead at the moment, so I'd suggest working on stuff on your fork 'til I have time to pick it back up. Going with the first option seems reasonable given how things are constructed right now though.

As long as you(re still able to push onto composer packages, everything will be fine 😜
