Feature Request - Support :hmac-sha1

[bpringe]

I tried running the following but it appears there is no method implementation for :hmac-sha1. Will this be added?

(mac/hash payload {:key my-secret :alg :hmac+sha1})

I get an exception:

No method in multimethod 'engine' for dispatch value: :hmac+sha1

And I see that the method does not exist in the source.

Quickest way to achieve this is to add new dispatch to multimethod, like this:

(defmethod mac/engine :hmac+sha1
  [options]
  (let [digest (hash/resolve-digest-engine
                 (:digest options :sha1))]
    (assert digest "Invalid digest engine.")
    (org.bouncycastle.crypto.macs.HMac. digest)))

It can be done outside of library in your own code, so you don't need to wait for new release :)

PR is welcome ;)
