Cause is that some pages have the onResponseReceivedEndpoints key
at the top level with useless stuff in it, and the extract_items
function was searching in that instead of the 'contents' key.
Change to use if blocks instead of elif blocks in the
extract_items function.
Add channel tabs to the channel template and script
Update continuation token to request different tabs
Add support for 'reelItemRenderer' format required to extract shorts
Does not work for videos that require decryption because
decryption is not working (giving 403) for some reason.

Partial fix for #146
The base url will be randomly missing.
Take one of the listed captions urls which already
has the &lang and automatic specifiers. Then remove these
specifiers.

Allows for ranked preferences for h264, av1, and vp9 codecs in
settings, along with equal preferences which are tiebroken using
smaller file size.
For each quality, gives av-merge a list of video sources
and audio sources sorted based on preference & file size. It
will pick the first one that the browser supports.
Closes#84

Adds support for AV1-encoded videos, which includes any videos
above 1080p. These weren't getting included because they did
not have a quality entry in the format table at the top of
watch_extraction.py. So get the quality from the quality
labels of the format if it's not there.
Because YouTube often includes BOTH AV1 and H.264 (AVC) for each
quality, after these are included, there will be way too many
quality options and the code needs to choose which one to use.
The choice is somewhat hard: AV1 is encoded in fewer bytes than
H.264 and is patent-free, however, it has less hardware support,
so might be more difficult to play. For instance, on my system,
AV1 does not work on 1080p, but H.264 does. Adds a setting about
which to prefer, set to H.264 as the default.
Also adds support for the lower quality mp4 audio quality, which
now gets used at 144p to save network bandwidth. For similar
reasons, this was not getting included because it did not
have an audio_bitrate entry in the table. Prefer bitrate
instead for the quality.

YouTube reverted the changes they made that prompted f9f5d5ba.
In case they change their minds again, this adds support for both
formats.
The liberal_update and conservative_update functions needed to be
modified to handle the cases of empty lists, so that
a successfully extracted 'music_list': [{'Author':...},...] will
not be overwritten by 'music_list': [] in the calls to
liberal_dict_update.

watch_comment api periodically gives the error "Top level
comments mweb servlet is turned down."
The continuation items for the new api are in a different
arrangement in the json, so changes were necessary to the
extract_items function.

Also moves some microformat extraction from
_extract_watch_info_mobile to extract_watch_info where it belongs.
_extract_watch_info_mobile is really only for stuff visible on the
page, and thus specialized for either mobile or desktop.
