Bug: 286444758
Test: jpegr_test.cpp
Manual test:
(1) append icc package to red-noicc.jpeg (attached in
the bug comment #1), then open the image with digital color meter, color measurement should be close to (255, 0, 0).
(2) Dump icc into a file and open the icc file on Mac, read data of each component (wtpt, r/g/bXYZ, r/g/bTRC) that should be the same as the samples in comment #10
