cats-effect 3.0 has reached RC state. Would be nice to provide -M or -RC build for this version. As it will contain breaking changes, I believe there will be a need to bump major version as well and adjust CI to build and publish from multiple branches.

I created a version, which builds against CE3 with this commit arixmkii@ae04eaf but it doesn't address CI and versioning in any way.

It also addresses #152 without losing ability to use different units for both Summary and Histogram.

I can provide changes as PR, when there will be separate branches for ce2 and ce3 (up to you, which one should be main for now), because obviously ce2 will be here to stay for some time.
