In the version of this article initially published, several sources of financial support were omitted from the Acknowledgments. The first sentence should have been “B.W. acknowledges support by the University of Zurich and the Swiss National Science Foundation (grant 310030_182703). J.B. acknowledges support by the ETH Zurich, ETH Project Grant ETH-20 19-1, and the Swiss National Science Foundation (grant 310030_172889/1).”
