+upgrade client version to

+```
+wac.SetClientVersion(2, 2123, 7)
+```

+- problem with stability of NeMO, whenever it comes to fault or error, it will force close, it will be much better if I add the restart NeMo in a specific feature:
+
+  1. Startup
+  2. Validate the coral
+  2. Send Message
+  3. Read Message
+
+- `log.Fatalf` will trigger the error and will be fail with a non-zero exit code
+- so the main function in this app is using asynchronous, and we need the async/await to retry the connection if failed
+- I need to research this again
+- so I hold this feature
+- and then I add the env key `WHATSAPP_CLIENT_VERSION_MAJOR` `WHATSAPP_CLIENT_VERSION_MINOR` and `WHATSAPP_CLIENT_VERSION_HOTFIX` so user can customize the whatsapp client version
+- the best way to do is by get the client version on device and set this automatically so we don't need to do this
+- in case the user using the old version of whatsapp, the env key must still exist
