cannot specify colormap for quiver

[yichechang]

using the following to specify colormap for quiver plot doesn't work

quiver.quiverplot_from_piv(
    piv=piv, 
    ...
    quiver_kwargs={'cmap': 'twilight'},
    ...
)

raising

TypeError: quiver() got multiple values for keyword argument 'cmap'

probably keeping DEFAULT_QUIVER_CMAP_ANGLE inside DEFAULT_QUIVER_KWARGS will fix the problem. but also need to consider dispatching for colorby='angle' and colorby='amp'

Current workaround

Modify this default value first before calling the plotter via

quiver.DEFAULT_QUIVER_CMAP_ANGLE = 'twilight_shifted'
quiver.quiverplot_from_piv(...)
