Benchmarks are slowed down when other modules are imported

[paulmillr]

I've spotted this after benchmarks were transitioned from common.js to ESM in 88c1aa3. Check out main branch.

• git clone [email protected]:paulmillr/noble-hashes.git && cd noble-hashes && npm install && npm run build && npm run bench:install
• Comment-out lines 14-28 in benchmark/hashes.js, run again. sha3 would become 25% faster

We need to investigate:

1. Why sha3 is 25% slower when other modules are imported
2. Why sha2 is NOT slower when other modules are imported. What's special about sha3?
3. Why everything was fine with common.js, but is slow with ESM?
4. Bonus issue: re-exporting isBytes slows-down performance considerably. See branch https://github.com/paulmillr/noble-hashes/tree/import-perf. Probably related.

To investigate this, v8/node.js profiling, memory dumps, etc may help.
