build: fix build on macOS Ventura | gnu 2020 [-Wc++17-extensions]

[stefanKuijers]

Since the node update from v18 to v19 mmmagic didn't compile anymore because missing C++ extensions. This merge request fixes that by changing the compiler and target platform.

Warning that it used to throw:

'static_assert' with no message is a C++17 extension [-Wc++17-extensions]

Error that is threw:

error: expected '(' for function-style cast or type construction

Please take a look and accept the merge request if you are happy with it.
Thanks in advance!

PS: I have not tested or it works on Mac if you OS is not up to date.
