Correctly convert types

Fix broken test

Add primitive type conversion. (#240)

The convert operator now supports converting from primitive types into
String, Number, Binary and Bool. This can helps comparing primitive values
to other concrete types, for instance checking for greater than or
boolean truth.

Instead of defining path as props they are now in ports (#239)

This PR improves upon #238 where the JSON paths where configured through properties - which led to unparseable port references in the resulting bundle with the message Message: "unknown port: bpi: jsonpath)bpi.USD.rate. That is because the properties would get translated into ports with names like bpi.USD.rate which confuses the parser.

I changed the operator to now accept the paths as inputs and map them to the outports via names given in the properties.
