#28 Performances of GuessInputStream.read() method are low

I'm experiencing very low performances of GuessInputStream read(); method
when i try to read one byte at a time.

On an 4 years old computer (Athlon 2400+?) dual core i get more than 1.6
seconds for reading a 160Kb file from a byteArrayInputStrem.

If i use the read(byte[]) with a 8K byte buffer the time goes down to 0.2
seconds.

Maybe some optimization is missing.

Seem there is a problem with the RandomAccessInputStream...

In fact it's a bit complicated to buffer the data and use the random access... so you
should avoid to use the read() method or buffer !GuessInputStream externally with a
!BufferInputStream.

In fact i also noticed that there is a slow performance decoding a base64 and i add
some buffer in the middle.
