The parser included in the ice package strictly adheres to RFC 7064,
however, this can be problematic when attempting to use ICE server URLs
that were automatically generated by a third party.
Twilio, for example, has been seen to send the following in its list of
ICE servers:
stun:global.stun.twilio.com:3478?transport=udp
which would require user intervention to sanitise before passing to
Pion.
This patch side-steps this aspect of ice.ParseURL by pre-stripping any
queries that may be present so that we can allow URLs of this form.
