feat: enable rendering MTPs to disk, from disk
- `bin/renderlocal` can take an `--mtp`, and any number of `--env`s (greater than 0) and render resources, writing them to `--out` - create a `LocalMustacheTemplateController` that resembles the mocked one used in tests - update tests to use `LocalMustacheTemplateController` - depends on proposed changes to `razeedeploy-core`
