This is cool! I didn't know you could do this kind of comparison without np.all()

This is only checking that the object reference is the same. If "new_data" is an array with the same values as the existing data array then it won't pass this check.

Intended use is something like this:

a, b, c, d # existing arrays

iw = fpl.ImageWidget([a, b, c, d])

# I want to replace only c

new = np.array(...)

iw.set_data([a, b, new, d])

# this will also end up replacing

a_copy = a.copy()

iw.set_data([a_copy, b, c, d])
