Conditionally invert axis to align annotations with elements

[droumis]

Fixes #112

Invert axis if the first kdim of the element is not an annotator kdim, ensuring overlaying annotations align with underlying elements.

Code

import holoviews as hv; hv.extension('bokeh')
import panel as pn; pn.extension()
import numpy as np

from holonote.annotate import Annotator
from holonote.app import PanelWidgets

annotator = Annotator({"x": float, "y": float}, fields=["description"])
bounds = (-1, -1, 1, 1)
data = np.array([[0, 1], [1, 0]])
img = hv.Image(data, kdims=['x', 'y'], bounds=bounds)
img_right = hv.Image(data, kdims=['z', 'y'], bounds=bounds)  # y as second kdim! so HSpan

left_plot = annotator * img
right_plot = annotator * img_right
layout = left_plot + right_plot

annotator.set_regions(x=(-0.15, 0.15), y=(-0.25, 0.25))
annotator.add_annotation(description="Test")

layout
