made SparseCtrl automatically context-aware so that contexts are easier to deal with
fp8 support for SparseCtrl
cleaner lowvram support for SparseCtrl
implemented 'cn_extras' for weights to allow Timesteps Keyframes to be able to schedule additional values associated with weights
fixed bug where less condhint images than expected into any ControlNet causing weird behavior with context options
all 'extension' of too few masks/condhint images is now done by using the last image/latent/mask instead of ComfyUI's default repeating (will make passing in too few images match up expected behavior with AnimateDiff and IPAdapter)
