Also remove cr from file

[filintod]

When executing on github actions on a windows platform, it can happen (depending on your .gitattributes setting or lack of settings), that the golden files will also have carriage return.

This PR removes it from the file when reading it.

Another option would be a documentations about adding .gitattributes file to the repo with * text=auto eol=lf

Thank you for the pull request! It has been a while since I've encountered this problem, but from what I remember I think the preferred solution is to use .gitattributes. In particular I think it's risky to modify the expected value. If the golden package is used with []byte those CR bytes may not be appropriate to remove.

I think it would be better to document the .gitattributes setup to prevent the problem. A section in the golden package godoc would be great!

Makes sense, I'll change this PR to be a doc change in the next days. Thanks

@dnephin please take a look when you have some time. I added the .gitattributes info to the global variable that defines the normalization.
