Description Brady Eidson 2020-03-08 10:06:30 PDT 
Remember completed subranges during incremental PDF loading

We'll often get asked for the same range twice, or for range contained in previously requested ranges.

To make that (orders of magnitude) more efficient, we should remember which ranges in the PDF buffer have previously been requested.

This relies on the patch in https://bugs.webkit.org/show_bug.cgi?id=208790 landing first (hence lots of failures)
