252 add closest point on rectangle to circle dev

[Johnnyg63]

Added a closest method for rect to circle in order to support collisions.

// closest(r,c)
// Returns closest point on rectangle to circle
template<typename T1, typename T2>
inline olc::v_2d closest(const rect& r, const circle& l)
{
// Johnnyg63
const auto pX = std::clamp(l.pos.x, r.pos.x, r.pos.x + r.size.x);
const auto pY = std::clamp(l.pos.y, r.pos.y, r.pos.y + r.size.y);
return { pX, pY };
}

I know its been a while, but this PR is a mess probably because its against main and not develop :P

[Johnnyg63]

Oh shoot , sorry meant for it to go into develop, I ll do it again correctly

[Johnnyg63]

Closing, will create a new PR to for this as it is pointing to main not develop
