ComfyUI-DareMerge
Merge two checkpoint models by dare ties (https://github.com/yule-BUAA/MergeLM), sort of. Now with TIES.

- In general, one means keep first model, zero means keep second model
- For DARE, we use the base model to determine which values to protect or include. It is optional, and if not provided will ignore exclude_a, include_b, threshold_type, and invert.
- For TIES, we can use the sum of the delta ties (as in the paper), or the count, or off to disable.
- Larger density means to include more of the second model
- Larger exclude_a preserves more of the first model
- Larger include_b allows more of the second model
- input, middle, and out are the block region weights.
- threshold_type is the way we determine where our threshold lies in our distribution since we use chunks, quantile will err towards the sparsity, median will use the chunk median.
- invert is whether we invert the threshold, so we keep the weights that are below the threshold instead of above.
