README typo

[awb99]

In the Readme, the Filestore example is wrong.
It uses konserve.memory,
but should say konserve.filestore

incorrect:

(ns test-db
  (:require [konserve.memory :refer [connect-fs-store]]
            [konserve.core :as k]))

(def my-folder "path/to/folder")
(def my-db (connect-fs-store my-folder))

correct:

(ns test-db
  (:require [konserve.filestore :refer [connect-fs-store]]
            [konserve.core :as k]))

(def my-folder "path/to/folder")
(def my-db (connect-fs-store my-folder))

Good catch! Feel free to file a PR.
