Add bytes feature passthrough (#631)

This allows you to use a `BytesMut` as a `Buffer` with
`chacha20poly1305` (or other AEADs) by only including `chacha20poly1305`
in your Cargo.toml and not also having to include `aead` in your
Cargo.toml. This is similar to how `heapless` and `arrayvec` currently
have feature passthroughs.

Fixes #600
