Add some benchmarks for `github.com/rs/zerolog`. These aren't exactly the same as the benchmarks in the author's PR: 1. The author's benchmarks don't timestamp zerolog's output, which is why they're so startingly fast. 2. Zerolog's sampler is too simple for reasonable production use - it just blindly drops a percentage of logs, rather than reservoir sampling. Given that, I left out sampling benchmarks. After those two adjustments, zerolog ends up being a bit faster than zap (~50 ns) when not adding context, but much slower (~14000 ns) when adding fields. This seems like a reasonable price to pay for zap's configurability, thread-safety, and encoding-agnosticism. * DRY up Sprintf varargs * Update README again
