This command launches a goroutine that does the actual downloading of
the emotes so the client doesn't hang until the process is finished.
subscribers.json needs to be manually downloaded and added next to the
main executable for now. Eventually, it will download and cache this
file (for 24 hours, at a minimum).
Issue #10 should not be considered finished yet. This needs to be
tested a bit more with multiple channels. Ideally, some that exist and
some that don't to verify that it fails gracefully (ie, adds the emotes
it was able to download).
