v1.3.1

This small release fixes support of the Nyx rendering plugin. Besides, contact normal forces no longer biased by the friction coefficient nor the sliding speed, thanks to the new rigid solver option 'contact_resolution' that bounds friction against the normal force actually developed by the contact.

gs.contact_resolution.convex	gs.contact_resolution.signorini (new default)
