* Have `Field`s implement `PoseidonInterface` (#209)
* Have `Field`s implement `PoseidonInterface`
Rather than having a sort of "dummy struct" implement `PoseidonInterface` with the field as a generic param. I think this seems more natural and type-safe.
The type safety does come at a price -- it would be harder to do dynamic things such as taking `WIDTH` as a command line option -- but I think that's alright.
* Fix missed conflicts.
* cargo fmt fixes.
* Fix to accommodate changes in latest nightly.
