Support adding annotator indicator view but not edit to certain plots

[droumis]

For certain accessory plots that only share partial kdims with the annotator, we should find a way (aside from just disabling the toolbar entirely) to display annotations without allowing for them to be editable on these plots, which errors because obviously one of the kdims remains is unspecified.

For instance, in the following, we would want to disable annotator box creation on the side and top plots, but still have the annotations visible on them.

Code

import numpy as np
import xarray as xr

width = 6
height = 5
frames = 30

data = np.random.random((height, width)) + np.repeat([1, 0.5], width//2)[None, :]
data = np.transpose(np.array([data * (0.95 ** i) for i in range(frames)]), (2, 1, 0))

data_array = xr.DataArray(
    data,
    dims=["width","height", "frame"],
    coords={
        "width": np.arange(width),
        "height": np.arange(height),
        "frame": np.arange(frames),
    },
    name="data"
)

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

main = hv.Image(data_array.sel(frame=10)).opts(width=500, height=400)
right = hv.Image(data_array.mean('width'), ['frame', 'height']).opts(width=200, height=400)
top = hv.Image(data_array.mean('height'), ['width', 'frame']).opts(width=500, height=200)

# pn.Column(top, pn.Row(main,right))

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

annotator = Annotator({"height": float, "width": float}, fields=["type"], groupby="type")
color_dim = hv.dim("type").categorize(
    categories={"A": "red", "B": "orange"}, default="grey"
)
annotator.style.color = color_dim
annotator.style.alpha=.6
panel_widgets = PanelWidgets(annotator)
table_widget = AnnotatorTable(annotator)
annotator_widgets = pn.WidgetBox(panel_widgets, table_widget, horizontal=True)

pn.Column(annotator_widgets, (top * annotator).opts(toolbar='disable'), pn.Row(main * annotator, right * annotator))
