Subject: [PATCH] MNT: Switch to hatch build system

Hatch has a hatch-vcs plugin that wraps around setuptools_scm while
remaining flexible.

In contrast, setuptools_scm hijacks setuptools' file finding, making
package data management cumbersome. And flit handles dynamic version
metadata by importing, turning install-time dependencies into build-time
dependencies.
