Data channel support

[paulelsner]

Hi,
I tried the latest forked version and basically it looked good.
https://github.com/OpenVidu/mediasoup-sdp-bridge

But it seems like data channels are not supported at all. Tried to hack that in quickly, but seems like the limitation is then in mediasoup-client. the RemoteSDP class doesn't support data channels.
Is this feature planned or any idea how to quickly come around this limitation?

The offer I want to process is
v=0 o=- 5517116905148734918 2 IN IP4 127.0.0.1 s=- t=0 0 a=group:BUNDLE 0 a=extmap-allow-mixed a=msid-semantic: WMS m=application 9 UDP/DTLS/SCTP webrtc-datachannel c=IN IP4 0.0.0.0 a=ice-ufrag:dSCG a=ice-pwd:Ytb4hpMD0XInQhu9wRjyynVH a=ice-options:trickle\r\na=fingerprint:sha-256 07:77:7F:33:4E:5F:C0:ED:84:54:BD:C3:0C:09:3A:BD:6C:62:D7:55:57:44:89:6B:5D:AF:FC:95:26:F2:10:86 a=setup:actpass a=mid:0 a=sctp-port:5000 a=max-message-size:262144

the answer which is created right now is
v=0 o=mediasoup-client 10000 1 IN IP4 0.0.0.0 s=- t=0 0 a=ice-lite a=fingerprint:sha-512 A9:36:B1:9F:18:F3:45:75:65:F6:45:3E:E4:D2:C5:33:C9:51:37:79:E1:01:25:2D:F8:30:E8:8E:35:53:91:B6:9C:D7:0F:2E:71:5D:2A:77:69:B8:E7:86:F9:A4:18:3B:29:04:4C:EF:53:AC:89:EC:6B:8E:76:21:09:38:33:6C a=msid-semantic: WMS * a=group:BUNDLE

And Chrome doesn't like it
Failed to set remote answer sdp: A BUNDLE group contains a MID='' matching no m= section.

Thanks!
