Log2-spaced CDF buckets. Behind the histogram Cargo feature
(on by default).
Use to export a full empirical distribution alongside the headline p50/p99 percentiles - downstream tooling can reconstruct any quantile from the bucket cumulative sums without needing the raw sample stream.

buckets - Log2-spaced histogram of latencies. 64 buckets covering
[2^i, 2^(i+1))nanoseconds fori in 0..64. A full empirical CDF can be reconstructed from the cumulative sum of this array. Empty input -> all-zero buckets.
