Optimize C wsscp performance and add SSH options

- Replace busy-waiting usleep loops with select() for efficient I/O multiplexing
- Add 50ms timeouts to prevent blocking operations
- Maintain 1MB buffers for optimal throughput
- Add 3-second exit delay after SCP completion for clean shutdown
- Fix critical bug in setup_tunnel return codes to prevent segfaults
- Correct memory management in argument cleanup to avoid corruption
- Add StrictHostKeyChecking=no option to wsscp and wsssh in both Python and C implementations
