Add example nested Variant values that are not JSON encodeable

Variant is a binary format similar to JSON but allows more types in its value fields.

However, at the time of writing, I could not figure out how to create nested structures other than via JSON, which limits the type of the fields. I tried Apache spark, but to no avail.

Thus, we have values such as the following (valid JSON):

{ 
  "field1" : 123.455
}

However, there are no example values for data like this (where the field's value is a signed 8 bit integer):

{ 
  "field1" : 123u8,
}

This ticket tracks adding example values for Variants for nested data that is not JSON encodeable (e.g. with timestamp and other types of fields)
