Add blacklight-query bin

[dphiffer]

This PR changes how the query script gets invoked, either with an arbitrary filename argument or by accepting the URL list from stdin.

Before:

cd blacklight-query
npm run main

After:

./blacklight-query urls.txt
echo "https://themarkup.org/" | ./blacklight-query

I have not tested out the global install scenario, but I assume it would allow you to run blacklight-query from anywhere.
