DTS-HD Master Audio

Currently Spek only decodes the core (lossy) of DTS-HD Master Audio.

I've come to this conclusion after converting one DTS-HD MA track to FLAC and comparing their spectrograms: while they should have been the same, there was a frequency cutoff on the DTS-HD MA track spectrogram which didn't appear on the FLAC track one.

It would be nice if it could decode the entire signal (the core and the lossless part).

Allowing to select stream (and channel) is issue #18.

For DTS-HD (and other formats containing both lossy and lossless streams) I think it makes sense to select the lossless stream. Could you create a small sample I could use for testing?

Here you are: http://bit.ly/W2Gp4J (from this useful website: http://www.demo-world.eu/trailers/high-definition-trailers.php).

I converted it to FLAC using eac3to with ArcSoft DTS Decoder (one of the few methods, if not the only, working).
