Merge aggregate and non-aggregate dataset examples in query result TSVs

[alyssadai]

At the moment, we have examples of:

• one human-readable results TSV
• one aggregated human-readable results TSV
• one machine-readable results TSV

for the query tool.

But the reality is is that there two primary types of downloadable results files (human-readable and machine-readable), and either can have a combination of both aggregated and non-aggregated datasets. We should make the examples reflect this by having only two example results TSVs, each with one 'protected' dataset in it. At the moment, there is no example of what a protected dataset in a machine-readable TSV looks like.
