orange dc3f2980db Removes FMA check for matrix multiplication 
Removes preprocessor check for FMA instructions in matrix multiplication functions.
This simplifies the code and relies on the compiler's ability to optimize the
code based on available hardware support. The assumption is that modern
compilers will automatically utilize FMA instructions if available, and fall
back to alternative implementations if not.

Billy Robert O'Neal III ee8073ceb4 Don't name std::fmodf. 
The C standard library function fmodf is not guaranteed to be in namespace std, and in fact is not with a default Ubuntu 24.04 installation, leading to the following compile error:

```

Only the 'sufficient additional overloads' of `fmod` are guaranteed to be in `std`. Since this is clearly intended to call the (float, float) overload, explicitly cast `((green - blue) / delta)` (which is a `double`) to `float` and call the name in `std` as suggested by the diagnostic.

OMath is a 100% independent, constexpr template blazingly fast math library that doesn't have legacy C++ code.
It provides the latest features, is highly customizable, has all for cheat development, DirectX/OpenGL/Vulkan support, premade support for different game engines, much more constexpr stuff than in other libraries and more...

## ❔ Usage ![APEX Preview]
Simple world to screen function
```c++
TEST(UnitTestProjection, IsPointOnScreen)
{
const omath::projection::Camera camera({0.f, 0.f, 0.f}, {0, 0.f, 0.f} , {1920.f, 1080.f}, 110.f, 0.1f, 500.f);
const auto proj = camera.WorldToScreen({100, 0, 15}); <br>
EXPECT_TRUE(proj.has_value());
}
```
