Make the --max-quality option support human-readable quality identifiers

[romanrm]

Hello,

Can you please support using the actual quality settings in --max-quality, and not just codes for video formats?

The user-facing "quality of video" nomenclature in YouTube is: "1080p, 720p, 480p", and so on.

So I expected I could download a video with:

--max-quality 720p

I do not care at this point whether this will be webm or mp4.

But this seems to be not possible. I have to look up what is the code for the format I need, then specify something like "-f 22/45" instead. And if in the future YouTube migrates to some h265 format with some "code 99 = h265 @ [1280x720]", my script will break, or not download the best possible format anymore.

And the current behavior of --max-quality is not even reliable in the first place, for example I want to include all 1280x720 videos (webm too), but I can not use --max-quality 45, because that will also match 1080p mp4, which is 37. DUH!!!

Available formats:
37 : mp4 [1080x1920]
46 : webm [1080x1920]
22 : mp4 [720x1280]
45 : webm [720x1280]
35 : flv [480x854]
44 : webm [480x854]
34 : flv [360x640]
18 : mp4 [360x640]
43 : webm [360x640]
5 : flv [240x400]
17 : mp4 [144x176]

With the last versions you can use -f 'best[height<=720]'. Thanks for the report!
