Feature request: `name` field in `Bench`

[colinhacks]

I was writing a custom prettyprinter for tinybench and found myself wishing there was a way to attach a name field to a Bench instance.

new Bench({
  name: "my benchmark"
})

That way, I could have a self-contained logger function that I can pass a Bench instance into:

function myLogger(bench: Bench){
  console.log(bench.name);
  console.table(bench.table());
}

Happy to put in a PR if I get a greenlight from a maintainer 👍
