/**
An implementation of the [Vector3](https://create.roblox.com/docs/reference/engine/datatypes/Vector3)
Roblox datatype, backed by [`glam::Vec3`].
This implements all documented properties & methods of the Vector3
class as of March 2023, as well as the `new(x, y, z)` constructor.
This implements all documented properties, methods &
constructors of the Vector3 class as of March 2023.
Note that this does not use native Luau vectors to simplify implementation
and instead allow us to implement all abovementioned APIs accurately.
