Hi thanks for the lib! I wonder whether it is reasonable to be auto-generated from the grafana schema https://github.com/grafana/grafana/blob/main/kinds/dashboard/dashboard_kind.cue. By doing that, we can, for example:

1. Always be up-to-date, no missing fields
2. Allow importing a dashboard JSON into grafanalib (for further customization)? #608 will be much easier
