N3Lexer: allow typeIRI tokens in line mode (closes #32) (#41)

* N3Lexer: allow typeIRI tokens in line mode (closes #32)

See https://www.w3.org/TR/n-triples/#grammar-production-literal
and https://www.w3.org/TR/n-quads/#grammar-production-literal

* N3Lexer: allow blank tokens in line mode (closes #34)

Blank nodes are allowed as subjects and predicates in n-triples and n-quads -
see https://www.w3.org/TR/n-triples/#grammar-production-subject and
https://www.w3.org/TR/n-quads/#grammar-production-subject (in n-quads
also as graphs).
