Build with mypyc 1.2

Several new versions of mypyc has been released since the last upgrade, and they include some performance improvements which could make the compiled version of Black run faster.

The latest version of hatch-mypyc allows being installed next the 1.x series of mypy.

I chose mypyc because it has already been out for a little while, and should probably be quite stable by now, but can also try a different version!
