Modified to use new case-sensitive lowercase logrus import

Sirupsen changed their github account to sirupsen, so this title-case import will have issues with projects using the new lower case import.

Updated to use the new lower-case version.

This is great, but I'd just like to note that personally I find it preferable for libraries to return errors rather than logging, unless It simply defines a log interface and I can provide my own implementation to harmonise it with the importing app logging.

I agree, but I was just getting it working first, I haven't gone back to that project again and I'm not sure this is even maintained anymore.

Depending on the dep management tool used, this PR can indeed be pretty useful. Would like to get this in also @janeczku
