colorbar now has a location keyword argument

The colorbar method now supports a location keyword argument to more easily position the color bar. This is useful when providing your own inset axes using the cax keyword argument and behaves similar to the case where axes are not provided (where the location keyword is passed through). orientation and ticklocation are no longer required as they are determined by location. ticklocation can still be provided if the automatic setting is not preferred. (orientation can also be provided but must be compatible with the location.)

An example is:

import matplotlib.pyplot as plt
import numpy as np
rng = np.random.default_rng(19680801)
imdata = rng.random((10, 10))
fig, ax = plt.subplots(layout='constrained')
im = ax.imshow(imdata)
fig.colorbar(im, cax=ax.inset_axes([0, 1.05, 1, 0.05]),
             location='top')
