/**
 *
 * Type that takes an array and a number and returns an array of arrays of the specified size
 *
 * 튜플과 숫자를 받아 지정된 크기의 튜플로 분할된 튜플을 반환하는 타입
 *
 * @params A - Array to be chunked / 분할할 튜플
 *
 * @params Split - Size of each chunk / 각 청크의 크기
 *
 * @returns
 * Array of arrays of the specified size / 지정된 크기의 튜플로 분할된 튜플
 *
 * @example
 * type cases = [
 *   Expect<Equal<Chunk<[], 1>, []>>,
 *   Expect<Equal<Chunk<[1, 2, 3], 1>, [[1], [2], [3]]>>,
 *   Expect<Equal<Chunk<[1, 2, 3], 2>, [[1, 2], [3]]>>,
 *   Expect<Equal<Chunk<[1, 2, 3, 4], 2>, [[1, 2], [3, 4]]>>,
 *   Expect<Equal<Chunk<[1, 2, 3, 4], 5>, [[1, 2, 3, 4]]>>,
 *   Expect<Equal<Chunk<[1, true, 2, false], 2>, [[1, true], [2, false]]>>,
