benchmark: add default value for settings param
It will cause an error when I try to import _cli.js
:
const CLI = require('./benchmark/_cli.js');
const cli = new CLI('');
TypeError: Cannot read properties of undefined (reading 'arrayArgs')
at new CLI (/Users/didi/Desktop/node/benchmark/_cli.js:28:34)
at Object.<anonymous> (/Users/didi/Desktop/node/benchmark/test-cli.js:2:13)
at Module._compile (node:internal/modules/cjs/loader:1120:14)
at Module._extensions..js (node:internal/modules/cjs/loader:1174:10)
at Module.load (node:internal/modules/cjs/loader:998:32)

So I try to use kEmptyObject
as default settings value for benchmark CLI.
