Add a method to obtain the total number of followers on twitchio.User

[graille]

Hello,

It would be nice to have a dedicated method to obtain the number of followers of a channel, without having to fetch the entire list of followers.

According to Twitch API Reference, this data is available in the response (the "total" attribute), but it is not used in TwitchIO. The only method provided hitting this endpoint is "twitchio.User.fetch_followers" which returns ALL the followers (500k+ at each request in my case, when I only want to know the number of followers O_O).

Would be nice to have a method like "fetch_followers_number" or "fetch_total_followers" which basically call the same endpoint as fetch_followers but with parameter first=1 to avoid useless Twitch server overload, and which would just return the "total" attribute from the response.
