Title: Booleans

Add `And` and `Or` binary operators to table Expressions. Add tests to ensure that they work in the three backends.

Note that I'm only doing binary operator booleans. This is because I want to avoid multiple inheritance in the TableExpr layer (multiple inheritance and multiple dispatch are hard to do simultaneously.) I believe that this will be simpler to do in the Scalar expr layer if we go down that route.
