Switch from ryu -> zmij for float formatting

[cijiugechu]

Which issue does this PR close?

N/A.

Rationale for this change

Prior art: serde_json switch to zmij.

What changes are included in this PR?

zmij already supports f32 formatting, so switch from ryu to zmij.

Are these changes tested?

Yes.

Are there any user-facing changes?

No.

I think we would need some benchmarks to justify switching crates

Thanks for this PR @cijiugechu

This looks like a dtonay special

https://crates.io/crates/zmij/versions

It is only 20 days old (it is already on version 1). I think we should wait a while for this crate to percolate through the ecosystem and see how it matures
