[FR] Consider using a modern package manager

**Is your feature request related to a problem? Please describe.**

This repository is using `npm` as package manager which is known to have several pitfalls, especially being slower than the alternatives and having sub-optimal peer-dependencies and node_modules management.

**Describe the solution you'd like**

I have no opinion on which modern package manager to use but it seems reasonable to switch to either Yarn or PNPM depending on the needs and preferences of the maintainers.
