Hi, I would want to use core cosmos type urls in some consts/enums, but couldn't find them, are they exist? I did [this PR](https://github.com/cybercongress/soft3.js/pull/23/files), but realized that this should be done in Cosmos libs, not by devs in theirs projects. Or how to do it correct? <img width="583" alt="image" src="https://github.com/confio/cosmjs-types/assets/18665326/aae97dd7-5153-4459-b6bf-4153d52363b2">
