ytt provides a semver library

[mstergianis]

Describe the problem/challenge you have
I use ytt to package up software to be shipped and run by other people. That means that the people that run the software run it in a variety of environments and for some feature flags it's intuitive to have the operator declare a version of software that they're using, in order to tune the installation to the versions they use. For example, running on different versions of kubernetes (1.23.x vs 1.24.x) might lead you to change the kubernetes resources you create, or the parameters you provide to those kubernetes resources.

Describe the solution you'd like
A semver library as part of the standard library for ytt. It could even probably be a thin wrapper over something like Masterminds/semver

Anything else you would like to add:
I thought about writing this library in starlark directly, but I find it difficult to distribute ytt libraries (without inventing something like NPM...)

Lovely! I'll close this out if that's already being tracked there. I only checked for existing issues in this project 😂
