Reassigning an optional to itself is not optimal

[isidorostsa]

Reffering to this part. There might be a more idiomatic way to do this using cpp2's loops

RayTrayCpp2/src/inc/hittable_list.h2

Line 28 in 653d6ce

record = obj*.

Changed the implementation to call .and_then with side effects instead in: 8819a5e

Still feel like there is a better way to do this. Also did not actually utilize any C++2 features. Leaving open for now
