ed25519 decode / decompress

[1000i100]

I have ed25519 pubkeys.
I would like to check there validity.
The RFC say how to do that by decoding/decompressing to an x,y point : https://tools.ietf.org/html/rfc8032#page-11

Do y plan to add this to this lib ?

This is unconditionally and automatically done every time you use them.

In the public APIs, keys are always compressed as a single coordinate + the sign of the other one. So, recovering the second coordinate is necessary. Applications don't have to do anything.
