pw-cat: fix DSD file reading

Browse source 
Now that the server asks for the right amount of samples for DSD, just
give it the right amount of samples without doing some weird scaling.

Make a method to calculate the size (stride) of one sample, which
depends on the interleave and channels of the stream.

See !2540
