Add US-200 support with backward compatibility 

- Add USB_PID_TASCAM_US200 (0x8034) product ID constant
- Introduce MODE_VAL_STREAM_START_US200 (0x0032) for device-specific stream mode
- Parameterize us144mkii_configure_device_for_rate() to accept stream_mode value
- Extend model naming logic to display "US-200" for US-200 devices
- Add US-200 to USB device ID table for automatic recognition
