This pactch makes to read a Jpeg data of #25274 correctly.
However this pull request needs to test with other CMYK Jpeg.
Since it seems to take a long time to create the CMYK JPEG, I created a pull request for the patch first.
I will add test after, I'm sorry.

@asmorkalov Thank you very much ! And I'm sorry that this comparing condition is not correctly exactlly. If norm() return 0, 1 or 2, this test should be passed ideally. However in now implementation it comparing to equal or not only. It is incorrect.

I created #25299 to fix it.

@sturkmen72 (This pull request has been merged, and this topic is not about this issue/pull request. So it is not better to continue here. I want to finish this reply as last.)

I am one of the many contributors, not important person with the authority to decide the direction regarding imgcodecs.

If you have any feature and/or improvement suggestions for imgcodecs, please could you create a ticket in here? If it is intested for me, I'l comment it. Thank you !
