Update all ed25519-dalek dependency to a published version

[coleFD]

We cannot publish crates that have github dependencies, and because we need no_std support, we are currently depending on a fork of the original ed25519-dalek repo since the published version will not compile. We need to find a solution to point towards a published crate in noise_sv2, so we can publish the crate and the crates that depend on noise_sv2.

fork and massage it meanwhile ?

So version 2.0.0-pre.0 is out now and is apparently "supposed" to be compatible with no_std, but the curve25519-dalek crate version is incompatible with the one used by snow which is another noise_sv2 dependency. There is a possibility that we can get snow to bump their curve25519-dalek dependency to the same one used by ed25519-dalek. With that being said, we need to confirm that the 2.0.0-pre.0 version is actually no_std compatible. Also as a note, the pre-release version has an updated api so we will need to adjust the noise_sv2 crate to match.

Wrt the toml dependencies (#456), forking and publishing may be the only way to go. I dont see this as a big issue since we only use it to parse config files.

@Fi3 pointed out @lorbax could look into this to see if we use it, if not we can close it.
