DEQ incorrectly described in doc string of QUEUE

[Gleefre]

From doc string of serapeum:queue:

CL-USER> (describe 'serapeum:queue)
;; <lines omitted>
    Remove an item with `deq':

        (deq (queue 1 2 3)) => 3
;; <lines omitted>

However, the correct result would be 1, not 3:

CL-USER> (serapeum:deq (serapeum:queue 1 2 3))
; => 1
