/**
 * `mapEach(map, fn)`
 *
 * Maps each value in `map` using `fn`, returning a new map with the transformed values.
 *
 * ```ts
 * mapEach(
 *     new Map([
 *         ["a", 1],
 *         ["b", 2],
 *     ]),
 *     (value, key) => value * 2,
 * ); // Map(2) { "a" => 2, "b" => 4 }
 * ```
 *
 * ```ts
 * pipe(
 *     new Map([
 *         ["a", 1],
 *         ["b", 2],
 *     ]),
 *     mapEach((value, key) => value * 2),
 * ); // Map(2) { "a" => 2, "b" => 4 }
 * ```
