Bring in refactor of the crate
...
This refactor was performed over several years. The crate was previously
focused on the Sapling circuit; it now encompasses the Sapling protocol,
and has types better suited to use in non-circuit contexts. Many of the
circuit helper types were moved into the `bellman` crate, and the Sprout
circuit was left in `zcash_primitives`.
