Function bucket_count_small

hail-fuzz/src/coverage.rs:304–316

Buckets counts such that entries that are hit a small number of times are consider interesting. EXPERIMENT: Alternative bucketing strategy to try to get coverage for individual edges to saturate earlier, (unused - block hits still appears to perform better).
