Fix triple null termination utf-16 little endian.

When fixing result[1] result[0] should be fixed as well.

Thanks!

This fixes #35

Great, thanks for the patch!

I'm seeing a panic for one of my MP3 files with this change when len(result[1]) == 0 (i.e. results[1][0] does not exist). I'll see if I can make a better test example to demonstrate.

[mkrogh]

Should that not be handled by the if len(result[1]) == 0 { check on line 367?

Actually my bad, line 373 and 374 should be switch around when done like this. My original patch was to append byte(0), but that felt wrong. But let me update the pull request.

Awesome, thanks. I ended up with the same change too, but then got carried away making other alterations.
