JSON issues

[reinvantveer]

When processing JSON source, a couple of issues arise that hamper transformation to RDF

• escaped backslashes in strings aren't unescaped
• line breaks in strings using \n aren't retained
• leading spaces in strings are droppped

The real trouble is in the processing of JSON arrays

• JSON arrays using unquoted values (booleans, numerals etc.) always throw errors

See data below, transform using java -jar RML-Mapper.jar -m multiple-datatypes/rdf/mosselenoesterhabitats.0.geojson/mosselenoesterhabitats.0.geojson.mapping.rml.ttl -o multiple-datatypes/rdf/mosselenoesterhabitats.0.geojson/mosselenoesterhabitats.0.geojson.nt -f ntriples multiple-datatypes.tar.gz

The errors can be reproduced by converting any of the unquoted values in the JSON to unquoted arrays, by the way
