Validation and limits

build() returns a validated deep copy. Each adapter validates again with prepareQuery, so a hand-made Query gets the same checks, and changing a value after passing it in changes nothing.

import { assertQuery, query } from 'dialectr'

const built = query().where('a', 1).build()
const copy = assertQuery(built)

assertQuery and prepareQuery return the validated copy and throw on an unknown operator or connector, a bad sort direction, an empty group, a sparse array, a value that is not a string, finite number, boolean, null, undefined or valid Date, or a forbidden key (__proto__, constructor, prototype).
