Suggestion: Update manual install steps to reference ComfyUI HiddenSwitch

[eliteprox]

The current instructions are not very specific about the steps to install comfystream manually. We can update the manual install steps to use hiddenswitch for ComfyUI instead of the normal version. This would provide a workaround to the issue of comfystream not working in ComfyUI => 0.3.27. See livepeer/comfystream#150
