Fix some warnings generated by Android Studio and do some code improvements
This commit moved the HLS parsing task to a separate method, did little performance improvements and used final where possible in the SoundcloudStreamExtractor file.
If a progressive stream is present in the transcodings, it's unnecessary to show twice an MP3 128kbps stream so if this is the case, the MP3 HLS stream will be not added to the audioStreams, else it will.
This commit also catch fetching errors in HLS manifests parsing and don't add the corresponding stream if an error occurs.
This commit tries to support SoundCloud HLS streams by parsing M3U manifests, get the last segment URL (in order to get track length) and request a segment URL equals to track's duration so it's a single URL.
This commit adds two new exceptions in NewPipe Extractor: GeographicRestrictionException and SoundCloudGoPlusException (which extend to ContentNotAvailableException). These exceptions allow showing different error messages to user when a content isn't available in his/her/its country (only used for now by SoundCloudStreamExtractor) or when the content is a SoundCloud Go+ track.
