I've replaced the usage of ByteArrayOutputStream/ByteArrayInputStream with the
new RandomAccessReadWriteBuffer.
PDFBox now supports decoded streams with more than 2GB as it uses chunks with a
default size of 4kb. The rw-buffer is used as out- and input so that it is no
longer necessary to copy the data to an intermediate byte array. In the end the
memory foot print is reduced one more time.
Additionally the chunksize is adjusted according to the estimated stream size
so that we don't waste to much memory if a pdf contains lots of small streams
such as the example from PDFBOX-5530
