Re-data

- data preparation - normalizing/filtering/cleaning/validation macros
- global metrics - enabling you to get metrics from the tables that aren’t time-based
- simplified config - we will be switching configuration to code only, and this will enable removing some of the currently a bit confusing config parts
- infra improvements - making it easier to contribute (GitHub actions testing your PR, Github action generating documentation, versioned documentation!)
