* 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.

No functional changes here. The biggest change was moving certain files into new directories like `plonk` and `iop` (for things like `Challenger` that could be used in STARKs or other IOPs). I also split a few files, renames, etc, but again nothing functional, so I don't think a careful review is necessary (just a sanity check).
