Commit a patched version of the opus patch for Asterisk 12.1.1
Asterisk 12 already has opus passthrough suport, so we had to clean up the original patch and make sure the rest is patched nicely.
Pay attention, this patch adds a new rtpmap of 125 to Opus as well. We've noticed that some SIP/WebRTC clients that utilize opus
may present 125 instead of 107 as the rtpmap for Opus - this is now catered as well.
