Ability to reduce central 'whiteness' in diverging colormaps about cmasher

[DanielYang59]

This is now possible with the combine_cmaps utility. It doesn't directly allow chop out a part of a colormap but you could achieve this by taking two sub_cmaps to avoid the central unwanted part, and recombine them, like so:

from cmasher.utils import combine_cmaps, get_sub_cmap, view_cmap

cmap_part_0 = get_sub_cmap("cmr.fusion", 0, 0.45)
cmap_part_1 = get_sub_cmap("cmr.fusion", 0.55, 1)

new_cmap = combine_cmaps(cmap_part_0, cmap_part_1)
view_cmap(new_cmap)

In this case I removed the central 10% but apparently you would need some further tweaking.

Thanks @DanielYang59 for your reply ! Indeed it seems that we now have API to support this use case so I believe this can be closed as solved in cmasher 1.8.0. Feel free to ping me if I'm understanding this wrong and the issue should be re-opened !

Hmm, that shouldn't be too hard to make. I can have a look at that.
