Clone: Use structuredClone instead of parse/stringify

[PTR-inc]

From node v17 onward there is the function structuredClone to deepcopy an object. Safer and maybe even faster.

this post shows its actually slower - nodejs/node#50320

Ah interesting! I got my impression from this discussion: what-is-the-most-efficient-way-to-deep-clone-an-object-in-javascript.

The fastness was just my quick interpretation of it being a 1 call versus a 2 call. But the extra complexity of properly cloning a complex object costs cycles, obviously.

The most important aspect was the safety of cloning an object, regardless of the complexity, and it being the 'official' way of properly cloning a object.
