Firestore now supports not-equal and not-in queries

Link to release notes

Apparently this came out a month now but I only stumbled across it in the docs yesterday.

Love this, I started using it immediately. The inability to write queries like this has been one of my main knocks on firestore, which has otherwise been very good to me.

Curiously, you still cannot query for non-null values, eg fieldValue != null (this is mentioned in the docs). I'm interested to know what exactly drives that limitation.
