Environment substitution not working with the new SparqlScriptProcessor.

[Aklakan]

Environment sustitution for IRIs such as in

$> FOO=bar sparql-integrate file.sparql

file.sparql:
SELECT * { BIND(<env:FOO> AS ?bar) }

stopped working after consolidating lots of logic into the SparqlScriptProcessor.

Although the SparqlScriptProcessor is configured with a parser that is wrapped with a post processor to perform environment substitution, the SparqlScriptProcessor invokes SparqlStmtUtils.processFile(...) which internally creates a new parser instance.

Hence,processFileneeds to be changed to accept a parser as an argument.

Should be long fixed - just tested this and it works as expected:

FOO=bar rpt integrate '(<env:FOO> AS ?x) {}' --out-format csv
# x
# bar
