Emulicious Improvements

- Support specifying `emuliciousPath` in the debugger preferences
- Stop customizing all the error messages without surfacing the actual errors its confusing
- Fix unreferenced `maxAttempts` when not specifying `emuliciousPath` and it fails to start
- Don't constantly retry connections thats handled internally by `dap.SocketTransport`
- Stop using `socket.socket` and `settimeout` which blocks
