2D Spectral Connectivity Plots

Hi there,

I鈥檓 looking to create a 2D sensor connectivity plot. What I鈥檓 after is what鈥檚 outlined in this discussion 2d head plot connectivity graph 路 Issue #149 路 mne-tools/mne-connectivity 路 GitHub from a couple of years ago.

It doesn鈥檛 look like it ever came to fruition, but I just thought I鈥檇 check? If not, are there any plans to implement this in the future? Whilst the 3D plots look good I feel these are generally a clearer way to plot connectivity.
