- download via presigned URLs via requests instead of boto APIs, remove boto
- follow-up to #1933 for streaming download improvements
- fixes datapackage.json in multi-wacz to contain the same resources
objects with: `name`, `path`, `hash`, `bytes` to match single WACZ.
- Add additional metadata to multi-wacz datapackage.json, including `type`
(`crawl`, `upload`, `collection`, `qaRun`), `id` (unique id for the
object), `title` / `description` if available (for
crawl/upload/collection), and `crawlId` for `qaRun`
