Fix: Added channel 5 to streaming services in options.json

[PDA-1]

Channel 5 was missing from the list, it caused a wrong title name to be calculated.

I tried submitting a fix on the GuessIt project, but it seems no one is maintaining it recently.
guessit-io/guessit#799

To test the fix, the file name "Motorway.Cops.Catching.Britains.Speeders.S07E05.1080p.MY5.WEB-DL.AAC2.0.H.264-RAWR/Motorway.Cops.Catching.Britains.Speeders.S07E05.1080p.MY5.WEB-DL.AAC2.0.H.264-RAWR.mkv" can be used.
It returns a wrong title name before the addition, and a correct one after it.

Thanks for the fix.
To ensure the fix doesn’t regress in the future, could you please add the problematic filename you provided to the testdata.json?

Also, because you’ve patched a vendored library, we need to properly acknowledge your changes. Please update the following section in the README.md file:

- [GuessIt 3.8.0](http://guessit.readthedocs.org) to extract information from file names and includes portions of code from [SABnzbd](https://sabnzbd.org/).

Done.
It's the first time I'm doing all that, so if not done correctly, I apologize.
