hist2dplot cmin functionality

[mduce6]

Hello, in matplotlib the min value of the colormap in hist2d plots can be manually set (cmin = value). I can't seem to get that functionality to work with my mplhep.hist2d and get the following error:

file "psd_fom.py", line 42, in rawplots
mplhep.hist2dplot(data,cmap = 'turbo', cmin=0)
File "/Users/mduce6/Library/Python/3.8/lib/python/site-packages/mplhep/plot.py", line 500, in hist2dplot
H[H < cmin] = None
TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'

after running
mplhep.hist2dplot(data,cmap = 'turbo', cmin=0)

When I don't include a cmin, I do get a plot. Only fails when cmin is included.
