Add Load Image Output node

[christian-byrne]

Adds Load Image node with remote widget. When refreshed, it re-fetches the values from the given route (in this case, files from output folder). This node can test the features detailed in Comfy-Org/rfcs#1 (lazy loading widget with remote source, changes to COMBO input spec).

Frontend:

• Add support for new COMBO input spec and lazy/remote COMBO widgets Comfy-Org/ComfyUI_frontend#2422 v1.9.7
• Add refresh button to remote (lazy) widgets Comfy-Org/ComfyUI_frontend#2494 v1.9.13
• Add support for image_folder field in node image input spec Comfy-Org/ComfyUI_frontend#2509 v1.9.13

this is breaking a lot of custom nodes and probably needs to be reverted and implemented differently

Which custom nodes?

Affects at least Video Helper Suite and Fill Nodes with their latest updates on ComfyUI Desktop. This is the offender, which you already pointed out on the VHS thread: https://github.com/Comfy-Org/ComfyUI_frontend/blob/0d6bc669f56f8aefcad11e39f3642a852efabf14/src/composables/widgets/useComboWidget.ts#L18

ComfyUI Desktop will fix this on the next release. In the meantime, reverting to a slightly older version of VHS and Fill Nodes in the Manager resolves the issue.

The changes from this PR in particular don't cause the bug. The bug happens because ComfyUI Desktop has a slight delay in updating frontend version. The bug is entirely on the frontend and its interaction with a few extensions.

Right. Except a "slight delay" in AI terms is practically weeks. This has made me seriously question using ComfyUI Desktop going forward. When a breaking bug like this comes up, "we'll fix it in the next release" is unaccapetable when no timeline is given and no interim solution is offered. Once this was discovered, an immediate release should have been offered for resolution. Instead, I had to discover how to resolve it myself, and still the next release is not available.

Fair enough. If you do decide to stop using the desktop app, maybe once we are out of the public beta phase you can give it another shot.

This isn't the experience we want for our users, though; the team spoke earlier about how this came about, and how we can prevent it from happening again.

still the next release is not available

Or is? https://github.com/Comfy-Org/desktop/releases/tag/v0.4.20

It wasn't yet out when I wrote that, but the release was still fairly quick, so kudos to the team for that.
