* Pass MODEL to AITemplate KSampler, but don't move to device
* Take alphas_cumprod from MODEL, -diffusers req, move alphas_cumprod only to device
* -checks for AITemplateModelWrapper, inpaint etc maybe still won't work, untested
* v2 should work, but will require module compiled for v2
* allow nodes to map over lists
* make work with IS_CHANGED and VALIDATE_INPUTS
* give list outputs distinct socket shape
* add rebatch node
* add batch index logic
* add repeat latent batch
* deal with noise mask edge cases in latentfrombatch
