This class applies a ASCII85 decoding to the stream.
The class is derived from InputStream instead of FilteredInputStream because
we can use the read(byte[], int, int) method from InputStream which simply
delegates to read(). This makes the implementation easier.
The filter is described in chapter 3.13.3 of the PostScript Language
Reference (third edition).
