LogC4 bug

Hi, Jed! How are you?
Seems like LogC4 curve is not decoding as it should. I haven't looked the code, but visually it looks way off.

Hi Anton! Good to hear from you again, hope you are doing well :D

Thanks so much for the bug report. I just tested this and can't seem to reproduce it... Piping a AWG4/LogC4 image into OpenDRT set to take that as input, and comparing to the same image data in DWG/DI interpreted the same way, seems to render identically.

By chance, are you testing a version from before this commit? There was a pretty big bug with the order of the input OETF transfer functions. Let me know, quite possible I'm missing something!

And I'm doing well! Spending way too much of my free time working on this silly project 😆
