[SR-Users] sdp extra \r\n in multipart body

[Daniel-Constantin Mierla]

Hello,

there is \r\n after

a=rtpmap:8 PCMA/8000

because

--uniqueBoundary--

is on next line.

Maybe is the fault of the code extracting sdp from multi-part body. Open
an issue on github bug tracker not to forget about it. If nobody looks
at it, I will try to do it, but it may take few days given traveling.

Cheers,
Daniel
