CHANGES:
- **`--mat_fmt=cool` by default**
NEW FEATURE(S):
- by default, an **un-binned** .cool file is generated
- if the end user provides a `--binning=INT` in pipeline, a balanced .mcool file binned at multiple resolutions will be automatically generated
- specify `--zoomify=False` to only generate a single-resolution binned .cool
- balancing arguments can be specified with `--balancing_args "..."`
- `--exclude=STR` in pipeline to remove chromosomes from the final matrix
BUG FIXES:
- check that provided fastq/bam files have the same length before starting
- cutsite doc is fixed
