Added an Extractor for Veyqo because of the issue https://github.com/rg3/youtube-dl/issues/11536
It the first time i use github this way and the first extractor i add.
But the download works fine.
Only the test_download part isnt checked. I could not get this working.
Read about it and tried different things. Possibly someone could help so i could check this in the future too.
