note that the two checkpoint models that are Stable Diffusion XL-based will not work on a CPU-powered space, because these are commented out because of hardware related issue reasons.
added another optional checkpoint model (installed by default)... this one is actually pretty good.
added one optional extension. (disabled by default, because using ADetailer on a CPU-powered space is just awful. useful if it's GPU-powered, I guess.)
ADetailer on a CPU-powered space is just awfully slow, so it's not installed by default for a reason... unless you uncomment it that is (hope it's a GPU-powered space).
force httpx to 0.24.1. the reason why, is that I've seen other spaces having startup issues like this, so it makes sense to just force it to a specific version so that it could still work trough.
