Adds a method to call a remote SPARQL end point, but without having to use Jena. #66

The reason why this is needed is the Jena tries to parse the SPARQL and complains
about non-standard extensions, e.g. by Blazegraph. Because the returned content is
XML, I opted for returning a byte stream, as passing around Java String sometimes
conflicts with XML content.

This allows a script like:

rawResults = bioclipse.sparqlRemote(
    "https://query.wikidata.org/sparql", sparql
)
results = rdf.processSPARQLXML(rawResults, sparql)

Full example: https://gist.github.com/egonw/ca4c348b9a2d1116efcdb55fa85dd158

This PR is linked to one for bioclipse.rdf, which I'll prepare next.
