* **registry:** registry requests now follow cache spec more closely, respect Age, etc ([9e47098](https://github.com/zkat/pacote/commit/9e47098))


### BREAKING CHANGES

* **api:** spec objects can no longer be realize-package-specifier objects. Pass a string or generate npa@>=5 spec objects to pass in.
* **integrity:** This PR replaces a pretty fundamental chunk of pacote.

* Caching now follows standard-ish cache rules for http-related requests.

* manifest() no longer includes the `_shasum` field. It's been replaced by `_integrity`, which is a Subresource Integrity hash string containing equivalent data. These strings can be parsed and managed using https://npm.im/ssri.

* Any functions that accepted `opts.digest` and/or `opts.hashAlgorithm` now expect `opts.integrity` instead.

* Packuments and finalized manifests are now cached using sha512. Tarballs can start using that hash (or any other more secure hash) once registries start supporting them: `packument.dist.integrity` will be prioritized over `packument.shasum`.

* If opts.offline is used, a `ENOCACHE` error will be returned.
