Following publication of this article, we were alerted via PubPeer to an inadvertent image duplication in Extended Fig. 7b in our paper. Upon carefully examining all the figures, we have discovered another duplication error in Extended Fig. 3g. The errors occurred during figure preparation by using placeholder images originating from similar areas of a well. The errors do not compromise the results or the conclusions of our work. We apologize to our colleagues for any confusion that this may have caused. The figures are now updated in the HTML and PDF versions of the article. For comparison, the original figures are available as Supplementary Information accompanying this amendment.
