stricter youtubedl format selectors (#3516)

* stricter youtubedl format selectors

make sure selectors avoid av1, and otherwise match as closely to the
maximum resolution enabled for transcoding

* add support for merge formats in youtubedl

* avoid vp9.2 in youtubedl to avoid any HDR

* move getEnabledResolutions, safer replace of imported extension

* add test for youtube-dl selectors
