Issue with shared axis labels on geographic axis

[lwq-star]

Referencing this conversation #155 , everything works normally, but looping through each subplot to plot causes a bug.

import ultraplot as uplt
import numpy as np

fig, axs = uplt.subplots(ncols=2, nrows=3, span=False, share='all', proj="cyl",
                         journal='nat2')
axs.format(abc=True, abcloc="ul", lonlabels='both', latlabels='both')

This is my example.

import ultraplot as uplt
import numpy as np

fig, axs = uplt.subplots(ncols=2, nrows=3, span=False, share='all', proj="cyl",
                         journal='nat2')
axs.format(abc=True, abcloc="ul", lonlabels='both', latlabels='both')

a = np.random.rand(10, 10) * 2 - 1

for idx in range(6):
    ax = axs[idx]
    m = ax.pcolormesh(a, cmap="viridis")
fig.colorbar(m, label="ac1", ticks=4, loc="r")

There might be some conflicts that have arisen.

The bug is caused by the colorbar I reckon. I think the colorbar somehow interacts with the labels on the geoaxes in particular by adjusting which ticks are on or off depending on the location of the colorbar. For a a singular plot it will also turn them off. PR welcome ;-)

[cvanelteren]

The colorbar somehow interferes with which labels are turned on or off. When plotting without it, the logic in 748 in the file geo.py correctly shows that the middle plot should have the labels on on the left. When the colorbar is added this never occurs. I suspect there is an interference through colorbar not directly in geo.py

[cvanelteren]

I think I know what is going on. The _get_border_axes logic does not account for when subpanel are added this creates the odd pattern you observe.

Think I found a fix for the GeoPart:

Need some minor fixes but this will be fixed soon. For users now turn off the sharing and it will work as it worked in the past (I think)

Fixed on main/
