Patch WanVideo model to use TeaCache. Speeds up inference by caching the output and
applying it instead of doing the step. Best results are achieved by choosing the
appropriate coefficients for the model. Early steps should never be skipped, with too
aggressive values this can happen and the motion suffers. Starting later can help with that too.
When NOT using coefficients, the threshold value should be
about 10 times smaller than the value used with coefficients.
