Richard Newman 19fc7cddf1 [query] Widen known_types correctly in complex or. (#424) r=nalexander 
* Part 1: define ValueTypeSet.

We're going to use this instead of `HashSet<ValueType>` so that we can clearly express
the empty set and the set of all types, and also to encapsulate a switch to `EnumSet`."

* Part 2: use ValueTypeSet.

* Part 3: fix type expansion.

* Part 4: add a test for type extraction from nested `or`.

* Review comments.

* Review comments: simplify ValueTypeSet.

This crate turns an algebrized Datalog query into a domain-specific representation of a SQL query, and then uses mentat_sql to turn that into a SQL string to be executed.

This subsumes both planning and query construction, because in Mentat the SQL query is effectively a query plan.
