Hi, thanks for making this project.
you can find attached below a few Luts I can't make work with your program.
Could you have a look? Is there any additional parameter I should specify?

Hi!
The issue for 3 out of 4 LUTs was related to reading files with CRLF line endings. Fixed it in PR #14.

As for the RedWideGamut_Log3G10 to Rec709.cube, the values specified in the file exceed the domain. According to the Adobe .cube LUT specification, if the domain is not specified, then the default is assumed (0.0-1.0). However, in that .cube file, I noticed values as high as 1.000003.
You can specify a custom domain limit in the .cube file. Adding the following line to your LUT should do the trick:

DOMAIN_MAX 1.000003 1.000003 1.000003

@JakubOchnik you are the best! Would you mind sharing a link to the Adobe .cube LUT specification?
