ytdl_hook, edl: add fps, samplerate codec parameters

Well, didn't help much in the case I was interested it.

 ``w``, ``h``
     For video codecs: expected video size. See ``codec`` for details.
 
+``fps``
+    For video codecs: expected video framerate, as integer. (The rate is usually
+    only crudely reported, and it makes no sense to expect exact values.)

+``samplerate``
+    For audio codecs: expected sample rate, as integer.

 The ``delay_open`` header is not part of the core EDL format. It may be changed
 or removed at any time, depending on mpv's internal requirements.
