Adjusted to rdfInterface 2.0.0

composer.json: bump rdf-interface to ^2

DatasetGettersTrait added

1.2.0

Iterator classes fixes

rdfHelpers\GenericQuadIterator::current() and rdfHelpers\GenericTermIterator::current() now return null if the iterator is invalid.

Adjusted to rdfInterface 2.0.0-RC3

rdfHelpers\TermIteratorInterface extended with following methods:

• contains(TermCompareInterface $term): bool allowing to perform in_array()-equivalent check
• getValues(): array<string> fetching string values of all terms in the iterator as array.
  • it allows syntax like $iter->getValues()[0] ?? $default
• intersect(array<TermInterface>|Iterator<TermInterface>|IteratorAggregate<TermInterface>|TermInterface $terms): self and skip(array<TermInterface>|Iterator<TermInterface>|IteratorAggregate<TermInterface>|TermInterface $terms):self allowing to quickly filter the iterator content

Small fixes

• Make compatible with both rdfInterface v1 and v2
• RdfNamespace::add() checks if the $iriPrefix isn't already registered
