broken in webui dev branch and add extension to index

[w-e-w]

two things

adding extension index

I was made aware of this extension by a comment so I want to add it the index

please check if this looks okay to you AUTOMATIC1111/stable-diffusion-webui-extensions#234

---

broken in webui dev branch

one thing that I do before adding an extension is I will test the extension

what I found out is that it seems the extension is broken in the current dev branch but working in 1.6.1 master
with my very limited JavaScript experience I believe the issue is due to your MutationObserver not firing

sd-webui-api-payload-display/javascript/api_payload_display.js

Line 84 in cae439e

new MutationObserver((_, observer) => {

since the dev branch is changing I'm not sure if this issue would be fixed automatically in the future, but I think making you aware of the issue before hand might be good

I think the issue is a DOM structure change that renders the new progress element under #txt2img_results_panel instead of #txt2img_results. I will submit a fix later.

I would hold on a bit not sure what AUTO would do
see AUTOMATIC1111/stable-diffusion-webui#14068
my guess is that if we move gradio 4.0+ more things will break

Temp fix submitted 3db2b44. I will keep an eye on A1111 changes to gradio 4.0.
