Add a check to don't show MP3 128kbps stream twice and catch IOException when fetching the HLS Manifest

Browse Source 
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.
