[feature request]collinear view

[jksr]

Could you provide a collinear view in CoolBox? will be very helpful in comparative analysis.

I made something inspired by the jointview.
code: https://github.com/jksr/CoolBox or https://gist.github.com/jksr/b9cd873f288b0827462fbc48d97bd38b
testing case:

This barely works ok for me, at least nothing visually wrong. but I'm not sure if the axes are complete aligned and styling could be improved.
It definitely will be very helpful if this is officially supported.

Looks good! I will try to support this.

I think this would be wonderful. To have coolbox + pygenomeviz (https://github.com/moshi4/pyGenomeViz) features together (or at least compatible so one can create a matplotlib figure combining both) would be a game changer for me!
