ArrayAnimatorWCS appears to be overriding user input slider labels

[DanRyanIrish]

Describe the bug

ArrayAnimatorWCS appears from the code to be overriding user input slider_labels: https://github.com/sunpy/mpl-animators/blob/main/mpl_animators/wcs.py#L103

Suggest the following replacement to the above line:

slider_labels = kwargs.pop("slider_labels", None)
if not slider_labers:
    slider_labels = self._compute_slider_labels_from_wcs(slices) + extra_slider_labels

To Reproduce

import sunpy

sunpy.map.Map(...)
etc
