[Icecast] OT: ban listeners

Hi Daniel,

Just chiming in with some intel - At Radio Mast <https://www.radiomast.io/>,
although we are running RSAS
<http://rocketbroadcaster.com/streaming-audio-server/> as an alternative to
Icecast, we have also observed this "axios" bot activity across our
streaming network. The axios user-agent corresponds to an HTTP client
library for Javascript/NodeJS of the same name. We have observed that the
bot is both enumerating streams (a spider) and downloading the actual
content of streams. It normally seems to listen for about 5 minutes. In
some cases, we have observed the bot listen for up to 15 hours. We're
unsure about who runs the bot or if this behaviour is intended. I think it
is likely to belong to some online radio directory, but this is just
speculation. The bot runs on Google Cloud Platform, based on the IP
addresses we're seeing it from.

Bot authors: If you're reading this, please set a unique user-agent that is
googleable so we can find out who you are (and so we can report bugs in
your bot), otherwise you'll likely be banned.
