Markduckworth/or queries (#6694)
Implementation of Firestore OR Queries without the public API. The public API will be released later. Several minor API changes are included in this release: Functions in the Firestore package that return QueryConstraints (for example: where(...), limit(...), and orderBy(...)) now return a more specific type, which extends QueryConstraint. This is a non-breaking change that will support OR Queries.

7+
now return a more specific type, which extends QueryConstraint. Refactoring and code that supports future features is also

included in this release.
