`roaring::RoaringBitmap::full().statistics()` panics if overflow checks are enabled

n_values_run_containers += runs.len() as u32;

The cardinality of the bitmap is exactly 2³² (across 2¹⁶ run containers), so it blows up when collecting the last container as it needs to store a value above u32::MAX.

Probably not a big issue, but it was a bit surprising to hit that first thing when trying to compare RoaringBitmap::new() and RoaringBitmap::full().
