Use ResizeObserver on DOM element

[sdrave]

Currently, K3D listens for browser window resize events. This causes issues when the DOM element into which K3D renders is resized for some reason while the browser window does not change its size. In particular, this often seems to be the case when when a K3D plot is placed into an ipywidgets container. By using a ResizeObserver on the targetDOMNode, this issue is avoided.

For example, on k3d-2.15.3 with

ipykernel==6.23.1
ipython==8.14.0
ipywidgets==8.0.6
jupyter-events==0.6.3
jupyter-lsp==2.2.0
jupyter_client==8.2.0
jupyter_core==5.3.0
jupyter_server==2.6.0
jupyter_server_terminals==0.4.4
jupyterlab==4.0.1
jupyterlab-pygments==0.2.2
jupyterlab-widgets==3.0.7
jupyterlab_server==2.22.1

I see the following issue:

With the proposed changes, the plot is correctly displayed.
