Overwriting option for matplotlib2vcs?

[lee1043]

vcs.colors.matplotlib2vcs(cmap, vcs_name=None)

https://uvcdat.llnl.gov/docs/vcs/misc/colors.html

When converting matplotlib colormap to VCS, by default vcs_name becomes same as the matplotlib colormap, or you can assign your own name. But if the name is already being used as one of original VCS colormap, it assign "_001" at the end of name.

run:

import matplotlib.pyplot as plt
import vcs
cm=vcs.colors.matplotlib2vcs('inferno')

message:

/Users/lee1043/anaconda2/envs/uvcdat-2.12/lib/python2.7/site-packages/vcs/colors.py:38: UserWarning: inferno colormap name was already existing, your colormap name will be: inferno_mpl_000
  (vcs_name, vcs_name_final))

run:

cm=vcs.colors.matplotlib2vcs('inferno', vcs_name='inferno')

message:

/Users/lee1043/anaconda2/envs/uvcdat-2.12/lib/python2.7/site-packages/vcs/colors.py:38: UserWarning: inferno colormap name was already existing, your colormap name will be: inferno_mpl_001
  (vcs_name, vcs_name_final))

Wondering if we can have "overwrite" option.

@lee1043 that's a nice idea, I'll add this. Might want to protect the vcs defaults such inferno though.

@doutriaux1 agreed, overwriting should be optional, not default.
