Added option for Digital cinema profile compliant codestream. This can be chosen by "-cinema2K" or "-cinema4K" for a 2K and 4K compliance respectively. The feature for tileparts has not been implemented in this version. Modification in image_to_j2k.c 

Added the Digital Cinema profiles (CINEMA2K and CINEMA4K) to the list of profiles recognized in the codestream SIZ marker segment. Modification in openjpeg.h,j2k.c
Added feature for constant quality within bitrate defined in Digital cinema standards. Modification in tcd.c
Modified the method of generation of buffer length. Modification in cio.c
