Specify library name and version: lib/1.0

This is also a good place to share with all of us why you are submitting this PR (specially if it is a new addition to ConanCenter): is it a dependency of other libraries you want to package? Are you the author of the library? Thanks!

Unfortunately GH doesn't allow you to make code suggestions for code that was touched in a PR. So let's post it as a simple i
comment.

I'm missing the test_type in the conanfile of the test_package. Apart from that LGTM

test_type = "explicit"

    def requirements(self):
        self.requires(self.tested_reference_str)

Tha ks for the suggestion. Working on my phone so sorry I did not add you as a co author

No worries, it was also copy-paste from my side 😉
