feat: re-export types from @helia/interface (#232)

`@helia/interface` lets us depend on the shape of a `Helia` without
having to depend on `helia` directly which is useful when you are
writing something lightweight and don't want to pull in libp2p etc
during an `npm i`, but in some cases we will have a dep on `helia`
so re-export the types from `@helia/interface` to not force people
to have a dependency on both.
