`SQLOperator` type doesn't include `NOT IN`

Is your feature request related to a problem? Please describe

Although there is an IN operator to filter for a value in a collection of possible values, the opposite NOT IN isn't available.

Describe the solution you'd like

Append the simple NOT IN option to the operator type:

type SQLOperator = '=' | '>=' | '<=' | '>' | '<' | '<>' | 'IN' | 'BETWEEN' | 'NOT BETWEEN' | 'IS NULL' | 'IS NOT NULL' | 'LIKE' | 'NOT LIKE';
