Add local pipeline development demo

Companion (demo) MR to eventutilities-python!3 (merged)
I added a demo of how to write local pipeline. It shows:
- loading mock data from a fixtures file
- feed it into a datastream, with schema validation
- running enrichment function on it
- collect results into a local sink, so they can be introspected and analysed.
