Description
Hi there,
RoaringBitmap 0.7.13 for Java has an "OrderedWriter" class which accumulates all values within the same highbits from a "int stream", so it touches each container only once. I didn't find anything like this on CRoaring implementation.
Is it something that is already in progress in CRoaring and can I implement it on my own and send a PR?
Thanks so much!

Research direction
Start by comparing Java RoaringBitmap 0.7.13's OrderedWriter with the existing CRoaring implementation. Trace how values from an int stream are accumulated by highbits and how containers are created or modified. Done means CRoaring has an equivalent OrderedWriter capability that touches each container only once and is suitable for a pull request.
