argument: Suppress cppcoreguidelines-pro-bounds-pointer-arithmetic

Eventually Fix this by replacing this argument class with CLI11.

```
../argument.cpp:63:31: error: do not use pointer arithmetic [cppcoreguidelines-pro-bounds-pointer-arithmetic,-warnings-as-errors]
    std::cerr << "Usage: " << argv[0] << " [options]" << std::endl;
                              ^
```
