`hashbrown` depends on `ahash` which depends on `once_cell`. Sadly, in matklad/once_cell#201 the `once_cell` maintainer decided they didn't want to do the work of having an MSRV policy for `once_cell`, making `ahash`, and thus `hashbrown` require the latest compiler. I've reached out to `ahash` to suggest they drop the dependency (as they could trivially work around not having it), but until then we simply downgrade `hashbrown`. `rust-bitcoin` also requires an older `hashbrown` so we're actually reducing our total `no-std` code here anyway.
