This moves the traits for defining an expression evaluator into sparrow-interfaces and the code for executing a sequence of expressions into sparrow-expr-execution..
This allows flattening the sparrow-expressions crate, and only using it as a test dependency in a wide variety of places. It is only needed at execution time.
This is preparation for adding sparrow-aggregations to implement the stateful aggregations.
