Dev compile for when M chip exists.

[iparask]

This is more for when someone installs pixell on a new Macbook for development. It does not replace the wheels that exist.

Meson will now check if the system is a MacBook with an M chip. When OpenMP is not found it will just compile without it. If the system is Linux or Intel based Mac it will error out. The same with windows because they are not supported.

If OpenMP is found, then all is well and it will continue as expected.

It also fixes another incompatibility error because of clang.
