Using https://github.com/asottile/pyupgrade
1. `__future__` imports and `coding: utf-8` were removed
2. Files were rewritten with `pyupgrade --py36-plus --keep-percent-format`
3. f-strings were cherry-picked from `pyupgrade --py36-plus`
Extractors are left untouched (except removing header) to avoid unnecessary merge conflicts
* Extract directly from the beta API when cookies are passed. If login cookie is absent, the extraction is delegated to `CrunchyrollIE`. This causes different metadata to be extracted (including formats and video id) and therefore results in a different archive entry. For now, this issue is unavoidable since the browser also redirects to the old site when not logged in.
* Adds extractor-args `format` and `hardsub` to control the source and subtitles of the extracted formats
Closes#1911
