Patch for Biff8DecryptingStream

You are right regarding the reading, readUShort - first we haven't implemented
writing for RC4-HSSF yet and I guess even when writing a broader datatype in a
smaller, the sign
doesn't matter, e.g. 200 (int) = 0x000000C8 becomes -56 (byte) and needs to be
back to unsigned when it's read ...

Is the attached patch for Biff8DecryptingStream working for you?
