feat: use setuptools_scm for versioning

Use `setuptools_scm` to generate version numbers from git as per the [Default versioning scheme](https://github.com/pypa/setuptools_scm/blob/main/docs/usage.md#default-versioning-scheme). It provides a convenient way to align version numbers with tags, and as a bonus, we can generate `dev` versions from any commit, and not just tagged commits.

When there is no git repo present (eg: inside a Docker container) fallback to version `0.0.0`
