  1. Remove incorrect atrac decode ptr nullcheck. 

    Already shown in decode test to be valid.

  2. Skip samples in the first chunk of atrac output. 

    This seems to be what the PSP actually does, although not sure.  The first
result is always smaller by this amount (numerous atrac files tested.)

  5. Fix seeking in atrac after the start. 

    Not sure the very start is right though, arg.

  7. Clamp the final sample count during decode. 

    Some games depend on / expect this, or else they'll let important data get
overwritten.

  8. Add extra frames if we run out of atrac data. 

    We could probably insert frames instead for GHA phase shifting, but this
will solve other bugs too, I think.

  9. Correct the end from sceAtracGetSoundSample(). 

    I think it's meant to be the last *valid* sample.
