More a questions about EdwardsPoint rather than issue.

[SergeStrashko]

Is there any particular reason why EdwardsPoint is not constructible from [u8;32] ?
Like here in Golang

[tarcieri]

It is, albeit by way of CompressedEdwardsY, which is is a newtype for [u8; 32].

That said, a more direct method might be nice.

[tarcieri]

I think it might be worth discussing adding an EdwardsPoint::from_bytes API.

[SergeStrashko]

I think implementation will use CompressedEdwardsY underneath anyway, and having two implementations doing exactly the same is root for confusion. I think leaving it as is is good option. And since now there is support for pks8 it might be redundant.

I believe #562 gives a method for this. It requires group though. @SergeStrashko does that work for you?
