Major performance problem for item with many authors

[dstillman]

citeproc-rs seems to have a problem when an item has many authors. For a single item with 448 authors, copying a bibliography to the clipboard — which generates a bib first in text and then in HTML — takes 17873 ms with citeproc-rs. With citeproc-js it takes 64 ms.
