I ran this on an arm mac, and also on x86-via-rosetta mac (which isn't quite the same as native, but it's the best I have). I did find one problem, which is that the packet forwarder misinterprets a response to the `x` packet which begins with an `O` as an "output" packet. I guess it needs to be taught that these can only come while the process is running. I'm still thinking about the best way to achieve that.

This change is definitely stress-testing the python packet parsing code as well. Before this, it was just handling a very limited about of traffic (just the packets that are explicitly sent by the lldb-server tests), but now it basically needs to forward entire lldb traffic.
