Extended expressions can contain "measures" which are aggregate functions. We should add an API to the top level builder for building aggregate measures. Note, aggregate functions are NOT (currently) expressions in Substrait and so they should not yield Expression objects and should not be addable to expressions in the same way that scalar functions are.
