std/crypto: implement the Hash-To-Curve standard for Edwards25519

https://github.com/cfrg/draft-irtf-cfrg-hash-to-curve

This is quite an important feature to have since many other standards
being worked on depend on this operation.

Brings a couple useful arithmetic operations on field elements by the way.

This PR also adds comments to the functions we expose in 25519/field
so that they can appear in the generated documentation.
