feat: Add custom operator (#868)

* feat: Add custom operator From #863 - It doesn't parse anything — I'm not sure how to parse ` SELECT 'a' REGEXP '^[a-d]';` with `REGEXP` as the operator... (but fine for my narrow purpose) - If we need tests, where would I add them? * Update src/ast/operator.rs --------- Co-authored-by: Andrew Lamb <[email protected]>
