Benchmarks

Benchmarks run on Thinkpad T460s - node 17.9.0 - yarn 1.22.18 / yarn 3.2.0 - using renovate 35.45.5 yarn.lock file (v1 first, then updating it)

(had to use -y because hyperfine would trigger stdin input)

``` $ hyperfine 'yarn-why -y yarn.lock lodash' Benchmark #1: yarn-why -y yarn.lock lodash Time (mean ± σ): 5.2 ms ± 0.2 ms [User: 4.2 ms, System: 1.0 ms] Range (min … max): 4.7 ms … 6.6 ms 417 runs

Warning: Command took less than 5 ms to complete. Results might be inaccurate.
