update Extended Data Table 1 with HF Fraxinus chronology

@camerondow35 , please update Extended Data Table 1 with n cores and dates range for the HF Fraxinus chronology.

Do you know if n.cores counts multiple cores from the same tree? So if there is a core1a and core1b, would n.cores = 2 or 1?

Good question. If it's labeled properly, it should could multiple cores from the same tree. If we were counting trees, it should be n.trees. At SCBI n.cores = n.trees (usually). At HF, most trees are cored more than once. This should be apparent in the original data files.

Thanks @camerondow35 !
