--run-pgx doesn't work on m68k

[southforkcode]

In PGXBinFile.read_blocks, there is an explicit check on the cpu and it appears only 65816 and 65c02 are supported.

        # Check the CPU tag
        pgx_cpu = self.data[constants.PGX_OFF_VERSION] & 0x0f
        if pgx_cpu == constants.PGX_CPU_65816:
            if self.cpu != "65816":
                print("PGX is built for the wrong CPU.")
                sys.exit(1)
        elif pgx_cpu == constants.PGX_CPU_65C02:
            if self.cpu != "65C02" and self.cpu != "65c02":
                print("PGX is built for the wrong CPU.")
                sys.exit(1)
        else:
            print("Unsupported PGX CPU.")
            sys.exit(1)

Is it possible to add support for PGX which is a simple file format that is useful for quick iterations as you can embed the header in the source?

This should be something that could be added as an enhancement that would work with the 68k version of the Toolbox (there will be a RAM boot option that isn't present in FoenixMCP proper).
