Can I remove `hdrhistogram` from metrics-util?

[PeterlitsZo]

I found metrics-util's Cargo.toml has config like:

[dev-dependencies]
hdrhistogram = { workspace = true }

But I find we do not use it in metrics-util at all... So, can I remove it?

Hmm, good eye. Yep, should be fine to remove. 👍🏻

Close because merged.
