[BUG] getSeriesWorks() does not return works after first page.

While testing my bot Archivist, we grabbed a very [lorg series](https://archiveofourown.org/series/60910) and discovered that AO3.js will not return works past page 1, because it doesn't deal with pagination.This is definitely an edge case series as most do not have 131 works. 😹

Locate getSeriesWorks() and inspect how it retrieves series pages. Reproduce the issue with the linked 131-work series, then verify that works beyond page 1 are returned rather than only the first page.
