new: rdf_attribute_prefix

[aMahanna]

Introduces a new parameter to the ArangoRDF constructor:

:param rdf_attribute_prefix: The prefix for RDF attributes (e.g., _uri, _value,
        _rdftype, etc.). Defaults to the original "_" symbol, but please NOTE
        that using an underscore "_", results in these attributes being treated
        as ArangoDB system attributes. Using "$" is an alternative non-system prefix.
    :type rdf_attribute_prefix: str

from arango_rdf import ArangoRDF

adbrdf = ArangoRDF(..., rdf_attribute_prefix="$")

adbrdf.rdf_to_arangodb_by_pgt(....)

# $uri, $label, $rdftype properties now stored in ArangoDB Documents instead of _uri, _label, _rdftype

Useful for replacing the _ underscore prefix to avoid complications around using system attributes (e.g arangodump masking)
