Some tests fail on windows

Reasons:

• Expecting \n and getting \r\n
• Unclosed streams preventing a temporary file from being deleted
• File layout differences \ and /
• No native library for brotli, because the brotli-codec dependency only shadows macos and linux native libraries.

I've already developed a patch that would fix all the problems excluding the brotli one. For that one we would have to wait until this https://github.com/rdblue/brotli-codec/pull/2 request is merged. I will link the merge request for the other problems in the next few days.

Is there a related ticket that i have overlooked?
