Currently, the COC marker overrides the SOP marker bit.
However, only the COD marker may set this value. This

The codeblock decoder checks whether the mqc decoder
has decoded the right number of bytes. However, this
check does not account for the fact that the mqc encoder's
flush routine adds 2 bytes of data which does not have to be
read by the decoder. The check is modified to

The JPEG2000 standard reserves marker values 0xFF30
to 0xFF3F to be used as parameterless markers. This
patch adds support to decode codestream with such
markers. This allows decoding of p0_02.j2k.
