> Support more operators in Output Sequence Type matching

>
> The ExpressionToolbox has a function called getOutputSequenceType that finds
> the output sequence type of the expression. Currently, the function only
> looks at variables created by the DataSourceScan operator. The function could
> support any operator that creates variables: Assign, Unnest, Aggregate, etc.
> The operators have not been added since they could create a recursive
> function traversing many operator and expressions. The process needs to be
> understood for each operator before adding it to the list.
