* `removeOrElse(map, key, orElse)`
*
* Removes the entry with the specified `key` from `map`, calling `orElse` with the map if the key doesn't exist.
*
* ```ts
* removeOrElse(
* new Map([
* ["a", 1],
* ["b", 2],
* ]),
* "a",
* () => null,
* ); // Map(1) { "b" => 2 }
*
* removeOrElse(
* new Map([
* ["a", 1],
* ["b", 2],
* ]),
* "c",
* (map) => map.size,
* ); // 2
* ```
*
* ```ts
* pipe(
* new Map([
* ["a", 1],
* ["b", 2],
* ]),
* removeOrElse("a", () => null),
* ); // Map(1) { "b" => 2 }
*
* pipe(
* new Map([
* ["a", 1],
* ["b", 2],
* ]),
* removeOrElse("c", (map) => map.size),
* ); // 2
* ```
