Are there any compatibility concerns? (can this version read the older bitmaps? can older versions read these newer bitmaps?)

@gianm I asked the same thing here: metamx/bytebuffer-collections#15 (comment)

So it sounds like this version can read older bitmaps, but older versions cannot read the newer bitmaps (because we are going to be writing optimized bitmaps). That sounds OK, since we tell people to update historicals first anyway.

On the bytebuffer-collections diff I think we should change the roaring version to a specific version rather than a range. Builds with version ranges are not reproducible, and it is good for builds to be reproducible.

@gianm released a new version with fixed dependency
