[YouTube] Update clients version and improve extraction of API key and client version of WEB client #890

  1. [YouTube] Improve WEB client version and API key HTML extraction 

    Common code in WEB client version HTML extraction has been deduplicated, usage of the Java 8 Stream API has been made and initial data fallback has been used as a last resort.
This means that the client version extraction from regexes will be used before this fallback, as it doesn't contain the full client version.
This can be used as a way to fingerprint the extractor, even if it seems to be not the case.

    …lient

The iOS version can be got easily in fact, by looking at the What's New section of the App Store' app page.

  3. [YouTube] Spoof more mobile clients 

    Additional parameters have been added to the player requests of ANDROID and IOS
clients:

- for both clients: osName and osVersion: their respective values are:
  - for the ANDROID one: Android and 12;
  - for the IOS one: iOS and 15.6.0.19G71.
- for the ANDROID client: androidTargetSdkVersion, with the Android SDK version
  corresponding to the Android version used in the player requests of this
  client. This parameter is now required with this client to be sure to get a
  correct player response, otherwise, the one of a video saying that this
  content is not available in this app and to watch it with the latest version
  of YouTube can be returned instead;
- for the IOS client: deviceMake, with Apple as its value.

The iOS version sent in the IOS client player requests has been also updated to
the version 15.6 of the OS.

Finally, a comment about the requirement to use the signature timestamp from
the player JavaScript base file for HTML5 player requests on videos with
obfuscated URLs has been added and replaces a previous one which may be not
true.

  4. [YouTube] Ensure that an additional player response is the correct one 

    If YouTube detect that requests come from a third party client, they may
replace the real player response by another one of a video saying that this
content is not available on this app and to watch it on the latest version of
YouTube. We can detect this by checking whether the video ID of the player
response returned is the same as the one requested by the extractor.
