Allow sample data for DataSet component in harness (pcf-start)

[cakhaing]

I want harness page to load the sample data from JSON files so that I can simulate the dataset component using data downloaded from Dynamics Web API. JSON files can be placed under pcf-script.

Expected result is attached.

I like the idea as well, a few more options to use real datasets.  preferably with less coding (eg. point it to a CDS or D365 datasource, pick an entity or provide a fetch query)... i know thats a bit of an ask.

Great idea! We are working on adding mock dataset data support in the harness.
