`raylib::Vector4` operator overloads

[sumandas27]

raylib::Vector4 doesn't have scalar multiplication and vector addition operator overloads even though raylib::Vector2/3 do. Raylib provides Vector4Add and Vector4Scale identical to Vector2/3 (which is what raylib::Vector2/3 overloads use). Adding these look simple, unless this was an intentional decision.

Definitely want these ones in 🙏

can i try solving this issue
i am trying to develop a physics engine of my own in c++ following ian millington's book
and i understand the concept of scalar multplication and vector additon and have implemented them before for 3D vectors
so i can i pls take a shot at this
