feat(monorepo): add one-version, a strict dependency conformance tool…

… for monorepos (#164)

This tool ensures that all workspaces in
your monorepo are using the same version of
a dependency, and also enforce strict
versioning strategy to ensure that all
dependencies are pinned to an exact
version.
