DataSomeValuesFrom and DataAllValuesFrom should support data property chaining

[althonos]

Once again, the grammar show support for

DataSomeValuesFrom := 'DataSomeValuesFrom' '(' DataPropertyExpression { DataPropertyExpression } DataRange ')'

DataAllValuesFrom := 'DataAllValuesFrom' '(' DataPropertyExpression { DataPropertyExpression } DataRange ')'

So the enum variants should store Vec<DataProperty> instead of DataProperty.

We should fix this, following the spec, but I don't want to change the API for 1.0. If we ever find an example where someone has used this, we can update for a later release.
