Support for live streams on nrk.no

[forthrin]

Recorded material works fine for this site, but not live streams:

~$ youtube-dl -v https://tv.nrk.no/direkte/nrk1
[debug] youtube-dl version 2016.12.18
[generic] nrk1: Requesting header
WARNING: Falling back on generic information extractor.
[generic] nrk1: Downloading webpage
[generic] nrk1: Extracting information
ERROR: Unsupported URL: https://tv.nrk.no/direkte/nrk1

If there are any workarounds, or other utilities which capture live streams, please post this here.

@dstftw: This can be done using streamlink. The issue may be closed if live stream support is out of scope.
