Include datasets and queries from JSONSki into benchmarks

Is your feature request related to a problem? Please describe.
The datasets described in the JSONSki paper are available on Google Drive, but are not incorporated into our benchmarks.

Describe the solution you'd like
We need the datasets included and experiments configured for those datasets. If wildcard selectors get implemented (#9), we can take the queries as-is. However, it is still beneficial to consider rewrites of these queries using the descendant selector not available to JSONSki for potential performance gains (and easier query formulations). This needs to be investigated.
