Define a new command, say \citeproc[ref], which saves the values of `ref` to a lua table, and at the end of the run, write that lua table to an aux .json file, call citeproc and store output to a new file, and on the second run read from that file. This is essentially how the old bibtex used to work.

Second, it creates a bunch of extra auxiliary files, which is always annoying. But I do agree that it will provide us with the ability to use the large number CSL styles.

the bib module can read lua files (or whatever)

i have no clue what csl is but I assume it's just some key / value thing 
as the bib module itself should to the logic
