Support TypedArray types...

[nearest-river]

TypedArrays are very helpful in certain situations... for example a Vec<i32> or a Box<[i32]> could be turned into an Int32Array which is very helpful

Rust

#[deno_bindgen]
pub fn mouse_pos(this: usize)-> Box<[i32]> {
  let this=unsafe { ..... };
  let pos=this.mouse_position();
  vec![pos.x,pos.y].into_boxed_slice()
}

export function mouse_pos(self: number|bigint): Int32Array {
  return lib.symbols.mouse_pos(self);
}
