Show scalebar parameters don't take effect if ar.calibration is not None

Describe the bug when using py4DSTEM.visualize.show, a dictionary passed to scalebar is ignored if the plotted image has a calibration parameter (e.g. virtual bright field images)

To Reproduce

import py4DSTEM
from py4DSTEM.visualize import show
import numpy as np

datacube = py4DSTEM.DataCube(np.random.rand(10,10,128,128))

datacube.calibration.set_Q_pixel_units('mrad') # arbitrary values to fill out calibration
datacube.calibration.set_Q_pixel_size(0.03)
datacube.calibration.set_R_pixel_units('nm')
datacube.calibration.set_R_pixel_size(3)

bf1 = datacube.get_virtual_image(mode='circle', geometry = ((64,64), 30))

show(bf1) # displays the default scalebar
show(bf1, scalebar={'position':'bl', 'color':'k'})  # scalebar still in same position and color as default

Expected behavior Would expect the default scalebar parameters to take effect, except for any that are passed to the function in the scalebar dictionary.
