Issue:
Release a 2.0.0-pre* that upgrades to curve25519-dalek 4.0.0-pre*
To eliminate pulling in additional copies of curve especially on memory constrained devices we might want to consider:

1. keeping prereleases in sync with their dependencies' prereleases
2. deprecating dependencies major versions (for less maintenance upkeep)


Discussion / hints:
I think this is complete?

https://crates.io/crates/ed25519-dalek/2.0.0-pre.0

That said, it'd be great to get another release out now that #285 is merged
