Removing unneeded dependencies like GLM and FMT

[MatusGuy]

GLM is just a struct with an x and y value and operator overloads. FMT is just snprintf.

More dependencies = harder to port. It's very disappointing having to deal with these libraries when they could've just been replaced anyway

Rather you mean glm::vec2 from GLM?

[MatusGuy]

Yes and that's the only thing we need from it
