🧐 Predicate util functions

import type { TypeOfDictionary, TypeOfValue } from "@lou.codes/types";
/**
 * Takes a `type` string and checks if given `input` is of that `typeof`. This
 * "patches" typeof so `null` is not `"object"` but `"null"` instead (rejected
 * proposal for lack of backwards compatibility, more details
 * [here](https://lou.cx/null-typeof)).
 *
 * @category Predicates
 * @example
 * ```typescript
 * const isString = isType("string");
 *
 * isString("value"); // true
 * isString(1); // false
 * ```
 * @returns Curried function with `type` in context that returns `true` if
 * `input` is of `typeof` `type`, `false` otherwise.
