and add a -GuardBits option to opj_compress. The recently-released SMPTE DCP Bv2.1 Application Profile (link below) says that the number of guard bits in the QCD marker shall be 1 for 2K content and 2 for 4K content. This change allows the number of guard bits to be configured, so that users of openjpeg have the control they need to meet the specification. https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=9161348 This is an alternative implementation of uclouvain#1388 that keeps ABI unchanged.
