Enable https in neuroglancer game

**Is your feature request related to a problem? Please describe.**
Currently, the streamlit neuglancer game endpoint doesn't have HTTPS listener configured. This is due to the issue that the embedded neuroglancer service does not load properly if the streamlit app runs in HTTPS mode. For security reasons, internet browsers don't allow a service running in HTTPS mode to invoke/request an HTTP service.

**Describe the solution you'd like**

- Find a way to have the embeded neuroglancer services to run in https

**Describe alternatives you've considered**
- See if a proxy service can be used that redirects HTTPS requests to the HTTP listener.
