Support computed columns in accessors

Description

Currently, computed columns are only supported with basic `mapper.get()` operations. They are not filled in by accessors, because user-provided queries won't necessarily have the column aliases required for computed fields to work.

We should provide a way to support computed fields with @Query. For example, the user could provide the target entity class and only the WHERE clause of the CQL query, and the driver would rebuild the full request.
