Paramater `remove_text` in `mpl_image_compare` decorator does not remove axis labels

Nobody has claimed this yet.

When choosing `remove_text=True` I would have assumed that the text for axis labels was removed along with the axis ticks and any titles. But it doesn't seem to do that.

The code uses `remove_ticks_and_titles` from matplotlib and that does not appear to remove the axis labels (See [matplotlib documentation](https://matplotlib.org/stable/_modules/matplotlib/testing/decorators.html)).

I'd propose updating the `remove_text` conditional as follows:

```python

if remove_text:
remove_ticks_and_titles(fig)
for ax in fig.get_axes():
ax.set_xlabel = ""
ax.set_ylabel = ""
```

If this seems reasonable, I can submit a PR.

Start by locating the mpl_image_compare decorator and its remove_text conditional, then inspect how the existing remove_ticks_and_titles call affects axis labels. Verify the behavior with an image-comparison test and consider the proposed label-removal behavior done when remove_text=True excludes axis labels as well as ticks and titles.
