## Message

```
Expose the elligator map for Curve25519

This is the same as for Edwards25519 without the y coordinate,
since it returns Montgomery coordinates, but it can be confusing
to call the Edwards25519 function while working on the
Curve25519 representation.

New protocols such as CPACE requires the map over Curve25519.
