Upgrades version of ed25519-dalek

[e-ivkov]

Description of changes

Upgrade from 1.0.0-pre.2 to 1.0.0-pre.3
And corresponding fixes for other lib versions and src files

Benefits

There is an issue with the usage of latest ursa (0.3.2) with latest libp2p(0.16.2): they have incompatible versions of ed25519-dalek (ursa - 1.0.0-pre.2 and libp2p - 1.0.0-pre.3). It could be solved only by downgrading libp2p to version 0.13.1 which is rather old now.

Therefore this PR is meant to fix that and make latest ursa and libp2p compatible, as they have rather intersecting user groups in my opinion.

Seems like this upgrade is blocked by rust-num/num-bigint#128 for now. It is needed to upgrade the version of num-bigint from 0.2 to 0.3.

num-bigint 0.3 hasn't been released. The highest it goes is 0.2.6 and that version is still tied to 0.5. I'm tempted to push my own crate that does work so this can be unblocked. I also need to update glass_pumpkin but have been stuck on this version as well. Perhaps I'll do that later today.

The 0.3 version of num-bigint was released on 12th of June. So hopefully we can also upgrade the versions here.

The asm build target seems to also fail on previous master branch commits with the same error: error: the legacy LLVM-style asm! syntax is no longer supported. So I guess this PR does not introduce new problems for asm.

There’s already a PR that needs to be merged that fixes the asm build error

So I think it is possible to merge this PR after the fix for the asm will be merged?

[mikelodder7]

Most likely. For now, I don't foresee any problem.

Approved provided we merge PR 123 first
