C++ standard 20 conflicting definitions of lerp function

[bonorumetmalorum]

On Ubuntu 22.04.3 LTS using G++ and Clang++ with CPP standard 20 there are conflicting definitions of the lerp function. Here is the full error message:

The lerp functions were added in standard 20: https://en.cppreference.com/w/cpp/numeric/lerp but for some reason MSVC does not throw any compilation errors here.

Have the fix for this ready to go, it just needs some more testing. Will close this when the release with the fix is put out.
