refactor bpf histogram indexing #249

Closed brayniac closed 5 months ago

brayniac commented 5 months ago

The previous BPF histogram indexing was based on a reduction of the algorithm in an older version of the histogram crate that had both an a and b component. The latest histogram crate replaced those with a single grouping power.

This change brings the indexing more in-line with the Rust version. Specific reductions and optimizations are made based on the specific values that we use throughout Rezolus.
