Subtitle support for TG4 (tg4.ie) site

[andyrozman]

• I've verified and I assure that I'm running youtube-dl 2017.07.23
• At least skimmed through README and most notably FAQ and BUGS sections
• Searched the bugtracker for similar issues including closed ones

There is one similar issue, but its for general support of TG4, which works for at least 8 months now. But subtitle doesn't work anymore

What is the purpose of your issue?

• Feature request (request for a new functionality)

---

As far as I can tell TG4 site is supported and it's been for at least 10 months... During my use with this site, I could also download subtitles, but this is not possible anymore...

I am not sure if the site changed or if application changed since I last used it (I used it with this site on at end of last year (before new year 2017)).

Like I said main download works, but it doesn't download subtitle anymore...

At end of the process you should have two files there:
Garfield 4 - 36 Adventures on Aruba Island _ Eachtraí ar Oileán Aruba-5416347428001.mp4
Garfield 4 - 36 Adventures on Aruba Island _ Eachtraí ar Oileán Aruba-5416347428001.ga.vtt

Garfield 4 - 36 Adventures on Aruba Island _ Eachtraí ar Oileán Aruba-5416347428001.ga.vtt is the subtitles file.
