git ssb

it would be more useful to callback to onEnd before cb, so that uses like this is possible:

      pull(
        File(blob),
        Hash('sha256', function (_, _id) {
          id = _id
        }),
        pull.drain(null, function (err) {
          if(err) throw err
          console.log(hash)
        })
      )

Unless there is something async after pull-hash, id won't be available. I would make a pr to fix this but currently in the process of getting ssb-blobs working right and that is interfeering

I agree, this would be good. I think I worked around it once using multicb.

I have a fix on my fork, but I pull requests arn't working for me yet

this is merged
