Add an endpoint to return the number of channels that a user is currently joined to.
I am trying to distinguish which viewers on my channel are most likely to be bots monitoring the channel versus people actually participating in the channel - even if they are just lurking. I would like to be able to check a given user_id and see if they are joined to multiple channels at once and if the number returned is over a given threshold mark them as likely bot accounts. I do not care what channels they are join into just the total number. Currently this information seems to only be available with user granted permission. Bot accounts are unlikely to grant any permission of course.
