Updated SamplerCustomAdvancedEfficient to work through comfyui Sampler Custom Advanced to support LTXV combined latent and future comfyui updates.
Added ScheduledCfgGuider, CFGFloatListScheduler (taken from my Wan-TimeToMove) to support higher cfg values at first steps without needing Wan-TimeToMove.
Removed redundant nodes.

An edit of efficiency-nodes's ksampler adv. (eff.) to let it accept custom samplers, schedulers (sigmas) and guiders through comfyui Sampler Custom Advanced and other native nodes. Supports:

internal slicing of the sigmas, useful for multi-stage sampling;
use of only positive, useful for sampling with cfg 1;
use of optional custom samplers, scheduler and guiders. Connect and use them or bypass them/leave the slots empty to use default widgets.

Suggested resources:

flowmatch scheduler: useful with video models using lightx loras;
ScheduledCfgGuider: supports higher cfg values at first steps.
