`import-rna` not compatible with pandas 2

[pontushojer]

I got this error running cnvkit.py import-rna.

Traceback (most recent call last):

I installed CNVkit from bioconda, the pandas version 2.0.2

iteritems is depreciated in v2.0.0 see https://pandas.pydata.org/docs/whatsnew/v2.0.0.html

Thanks for the report. According to pandas-dev/pandas#45321 it looks like the fix is to use items in place of iteritems.
