broadcaster_name not noted in return values of Get Channel info
Omits the description of "broadcastername" and as per https://github.com/twitchdev/issues/issues/3 it's the "dISpLaYNaME" of the caster not the username.
So we have to do a second lookup to get the
login for embed purposes

Closing this out now that it's documented. GitHub 3 will take care of the value.
