2D nested array of numbers deep copy

I kept only the test cases that produced usable results for me (ops/sec>100). Others I tried were nested `newArr.push()`, `JSON.parse(JSON.stringify())`, `arr.map(item => Object.assign([], arr))`, and `structuredClone()`. For me, `map concat` runs the fastest, followed closely by `map slice` and then `map spread`.
