Description

Currently, RelDecorrelator code only works for LogicalCorrelate. Decorrelating through Calcite would become much more flexible if it allows using custom implementations of Correlate. This would require refactoring all logical rels used in RelDecorrelator to the abstract ones(e.g LogicalCorrelate -> Correlate).
