CameraOrbbecSDK: catch ob::Error in init() instead of crashing

Device open can throw ob::Error (e.g. uvc_open access denied on macOS
without camera permission, or an unsupported stream config). The throw
was uncaught and aborted the whole process. Wrap the device-access body
of init() in a try/catch that logs the error and returns false so the
caller can handle the failure gracefully.
