Summary0001665: J2K data rate is hard-limited at 250Mbit/s even if the advanced pref is set
Description

Llooks as if dom/openjepeg currently applies a hard limit of 250MBit/s no matter if I set the allowed data rate higher than that. e.g. I allowed for 500MBit/s, and set the
datarate under DCP to 450 - the resulting DCP is exactly 250MBit/s. Both for 2k and 4k. The source footage is a 16Bit PNG in 1998/1080 with just color noise on the pixel level.

Looks like because openjpeg checks max_cs_size and limits it in opj_j2k_set_cinema_parameters
