[Rpcemu] Apple Silicon build of RPCEmu 0.9.3

Hello all

I've built a new version of RPCEmu 0.9.3 for Apple Macs.  The interpreter build is now a universal binary, which means it will run natively on both Intel and Apple Silicon (arm64) Macs.  It can be downloaded here:

The recompiler is not a universal binary, as arm64 is not a supported architecture for the dynamic code generation; if you run it on anything using Apple Silicon, it will still run under Rosetta 2.  I did look at the recompiler code to see how viable it was to implement an arm64 version, but unfortunately that's way beyond my capabilities.

Cheers

Tim
