To resolve #11

I think you have to change the required inputs to optional and set the defaults for latent1 and latent2 = None
Also, that'll mean adding a check for the case when both inputs are None, so maybe raise an error when that happens.

The specific use case I was working on was when there is a connection, but the upstream node sends None as an output. This happens with the Image Chooser Fabric node when no image is selected.

Can't see much point supporting the case where there is literally no Comfy connection - just remove the node!

If both inputs are None, it will output None, which seems like correct behaviour - give downstream nodes the option of how they deal.

Oh okay I see. I thought this was a UX thing.
