[YouTube] Add utility class to handle player requests fetching
This internal class, YoutubeStreamHelper, has to be public in order to be used by subpackages of the service's root one. It supports poTokens, HTML5 signatureTimestamp property, embed context and multiple InnerTube clients. It is meant to replace the corresponding methods in YoutubeParsingHelper, in order to reduce the class' size, code duplicates and improve its readability. It adds a new way to get age-restricted videos' streams, the only ones which are playable in YouTube embeds, which is not very common.
