* Faster iframe api based player extraction.
Uses the IFrame API to reduce the required download to less than 1/50 of the size.
* Remove debug code.
* Extract to two methods.
* Add tests for player URL extraction.
* Add assertThat for tests.
Without removing RunWith and SuiteClasses annotations (and the corresponding imports) in YoutubePlaylistExtractorTest and YoutubeMixPlaylistExtractorTest, some mocks cannot be generated, so the CI fails because of the missing mocks. Mocks of workings tests have been also updated.
Migrate YouTube comments to the desktop version by using the `next` endpoint of the InnerTube internal API.
With the desktop version, we are able to get the exact like count of YouTube comments (by parsing the accessibility data) (the current extraction is used as a fallback). We are also now able to get if the uploader of the comment is verified or not.

Here is now the requests which will be made by the `onFetchPage` method of `YoutubeStreamExtractor`:
- the desktop API is fetched.
If there is no streaming data, the desktop player API with the embed client screen will be fetched (and also the player code), then the Android mobile API.
- if there is no streaming data, a `ContentNotAvailableException` will be thrown by using the message provided in playability status
If the video is age restricted, a request to the next endpoint of the desktop player with the embed client screen will be sent.
Otherwise, the next endpoint will be fetched normally, if the content is available.
If the video is not age-restricted, a request to the player endpoint of the Android mobile API will be made.
We can get more streams by using the Android mobile API but some streams may be not available on this API, so the streaming data of the Android mobile API will be first used to get itags and then the streaming data of the desktop internal API will be used.
If the parsing of the Android mobile API went wrong, only the streams of the desktop API will be used.
Other code changes:
- `prepareJsonBuilder` in `YoutubeParsingHelper` was renamed to `prepareDesktopJsonBuilder`
- `prepareMobileJsonBuilder` in `YoutubeParsingHelper` was renamed to `prepareAndroidMobileJsonBuilder`
- two new methods in `YoutubeParsingHelper` were added: `prepareDesktopEmbedVideoJsonBuilder` and `prepareAndroidMobileEmbedVideoJsonBuilder`
- `createPlayerBodyWithSts` is now public and was moved to `YoutubeParsingHelper`
- a new method in `YoutubeJavaScriptExtractor` was added: `resetJavaScriptCode`, which was needed for the method `resetDebofuscationCode` of `YoutubeStreamExtractor`
- `areHardcodedClientVersionAndKeyValid` in `YoutubeParsingHelper` returns now a `boolean` instead of an `Optional<Boolean>`
- the `fetchVideoInfoPage` method of `YoutubeStreamExtractor` was removed because YouTube returns now 404 for every client with the `get_video_info` page
- some unused objects and some warnings in `YoutubeStreamExtractor` were removed and fixed

This method is needed for YouTube stream tests, because when all YouTube tests are ran, the signatureTimestamp is known (the sts string) so a different body than the body present in the mocks is send by the extractor instance.
As a result, running all YouTube stream tests with the MockDownloader (like the CI does) will fail if this method is not called before fetching the page of a test.
The strings playerJsUrl, sts and playerCode are now static in order to don't fetch again the JavaScript player at each time the signatureTimestamp is needed.
Catch every exception instead of only IOException and ExtractionException.
Add JavaDoc for fetchAndroidMobileJsonPlayer method of YoutubeStreamExtractor
Try to don't fetch again the first page of a YouTube channel when requesting a continuation of it by trying to store the channel name and the channel id into the next page using the ids field of the Page class.
