Is your feature request related to a problem? Please describe.
Custom emojis don't load on Megalodon from a gotosocial server, also does not work with the official client.

GTS requires auth for /api/v1/custom_emojis so the app can't fetch it. I have confirmed this in my server's log, Megalodon requests receive 401 from it.

I have opened a request there which lead to the above information: superseriousbusiness/gotosocial#2794

Describe the solution you'd like
Would it be possible to send the auth with the requests to that api endpoint to get the emojis working with GTS?

Additional context
Should this request be put into the Mastodon client bugtracker as well since this is forked from it? Although I have a feeling they don't care to fix it. Would be nice to have it working though.
