Important: This is slower and less scalable than
TriConstraintStream.join(UniConstraintStream, QuadJoiner) with a proper QuadJoiner predicate
(such as Joiners.equal(TriFunction, Function),
because the latter applies hashing and/or indexing, so it doesn't create every combination just to filter it out.

QuadConstraintStreamQuadConstraintStream.ifExists(Class, PentaJoiner). For performance reasons, indexing joiners must be placed
before filtering joiners.
This method causes Unchecked generics array creation for varargs parameter warnings,
but we can't fix it with a SafeVarargs annotation because it's an interface method.
Therefore, there are overloaded methods with up to 4 PentaJoiner parameters.
