Compatability of `copy-numbers` file schema with rrat

[dhoogest]

The requirement of the 'counts' column header in the copy-numbers csv presents an inconsistency with the rrat package, which returns a file with schema (see https://github.com/crosenth/rrat/blob/master/rrat.py#L253)

|--------+---------|
| tax_id | medians |
|--------+---------|

Curious what motivated the renaming, and what the best course of action might be for addressing the inconsistency.

The motivation was to make the header more general in case an outside user wanted to use their own derived copy numbers. If I remove the header requirement entirely and have rrat generate a headerless file would that be okay for the NGS16S pipeline?
