Add example data for the */data endpoint

Context Looks like there are some JSON examples for each in the repo. It would be good to include some parquet examples and maybe a notebook to change the parquet for testing (since it has embedded IDs).

Scope Create a simple Jupyter notebook with the next runs:

1. Creates Master-data (RockSample, Coring)
2. Creates a source dataset
3. Creates SampleAnalysesReport WPC
4. Creates SmapleAnalysis WPC
5. Uses testing parquet file to prepare the payload
6. Uploads parquet data
7. Uses JSON payload to test the JSON
8. Gets the bulk data

The notebook comes with a separate requirements.txt file.
