Upgrade zeroize dep

[k-bx]

I can't upgrade some of my project's deps due to curve25519-dalek requiring zeroize < 1.4. Is it possible to support later versions of zeroize?

[jrose-signal]

We've been waiting for upstream to release curve25519-dalek 4.0, which updates a bunch of dependencies: dalek-cryptography/curve25519-dalek#405. If that doesn't happen soon though maybe we can take this; the original reason for pinning it (again, upstream) was a disagreement about whether MSRV breaks should be semver breaks, and upstream has given up on that.

(This finally happened!)

@jrose-signal apologies for the confusion. I see the zeroize requirement is still there, and I also see there was a revert commit https://github.com/signalapp/curve25519-dalek/commits/lizard2 in here. Shall I re-open this issue? Or am I doing it wrong? Still getting an error when trying to depend on the latest presage:

[jrose-signal]

We're on the main branch now, because we realized our references to lizard2 in the libsignal-client sources meant we could never introduce breaking changes without breaking older versions of libsignal. (Thanks for the reminder to update our GitHub default branch.)

You can see curve25519-dalek is no longer the problem because of the listing of "requirements ^1". I'm not sure what the "locked to 1.3.0" indicates in this error message, though. Is it possible that that's in your lockfile, and you have a setting that keeps that from being automatically updated?

Apologies, doing this helped:
