Update LLImageJ2C::calcDataSizeJ2C for better 2k image support (#2406)
Adjusted calculations based on dimensions and assumed maximum block size so that higher discards (4-5) of 2048x2048 images can be decoded with aux/alpha.
(It should also work for dimensions larger than 2048.)
This function will now return a reliable discard 5 data size for unknown dimensions (w and/or h equals 0), which could be used in LLTextureFetch::createRequest to skip the header fetch and go right to a discard 5 decode.
Tested on OpenJPEG 2.5 with partial decode support (opj_decoder_set_strict_mode set to false).
Should work on KDU fine but might be a good idea to test.
