Fixes #674

This PR supersedes #505, and instead of using js-wacz for optimized WACZ creation:

  • generates an 'in-place' or 'streaming' WACZ in the crawler, without having to copy the data again.
  • WACZ contents are streamed to remote upload (or to disk) from existing files on disk
  • CDXJ indices are merged using the linux 'sort' command, and compressed to ZipNum if >50K (or always if using --generateCDX)
  • All data in the WACZ is read / written once
  • Should result in significant speed / disk usage improvements: previously WARC was written once, then read again (for CDXJ indexing), read again (for adding to new WACZ ZIP), written to disk (into new WACZ ZIP), read again (if upload to remote endpoint). Now, WARCs are written once, along with the per-WARC CDXJ, CDXJ is then merged on-disk, and all data is read once to either generate WACZ on disk or upload to remote.

A few initial comments/suggestions, continuing testing though so far it's looking pretty good!

Updated to latest released warcio.js / wabac.js, should be good to merge when everything else is resolved.

to make it clear the directory is not temporary (unlike tmp-dl) and should
be kept after a crawl is done, to allow further addition to the same collection
