fix(data-channel): stuck closing in Chrome

[Marcel-G]

Resolves #468

Currently the library does not properly implement the shutdown procedure for data channels closed by Chrome. In order for the data channel to fully close, it must receive a OutgoingResetRequest.

This was an existing issue in pion which has since been resolved here https://github.com/pion/sctp/pull/238

Reproduction

Using the examples/data-channels Run the JS test for closing data channels: jsfiddle Note the RTCDataChannels never enter closed state.
