[Biojava-l] Minor SCF patch

[Thomas Down]

Hi...

A user at Sanger has just pointed out that the sample data
in SCF files is always represented as unsigned bytes or
shorts.  The BioJava parser got this right for SCFv2 files,
but not for SCFv3.

I've just checked in a small patch to fix this.  Rhett: could
you check that this is okay?

We should add this to a list of things that need to be
backported to the 1.3 branch before 1.3.1 is released.

     Thomas.
