mpl.rcParams['mpl_toolkits.legacy_colorbar'] = False is deprecated in matplotlib 3.4 and will be defunct. It will need to be removed in the sidpy viz module.
This throws errors in current versions of matplotlib 3.7, I think (specifically I think 3.7 they finally deprecated this). So I think this would be good to remove from the viz module
