Still a bit raw, but gets the time required to determine the size of each chapter (for reading progress) down from ~25ms to 0-1ms. This is done by keeping the zipArchive open (so simple ;)). Probably we don't need to cache the spine sizes anymore then... --------- Co-authored-by: Dave Allie <dave@daveallie.com>
