[PATCH 2/5] piem-dispatch: Add command for copying public-inbox URLs

[Kyle Meyer <kyle@kyleam.com>]

piem-notmuch configures notmuch-show-stash-mlarchive-link-alist with a
custom piem function that's useful for grabbing the pubic-inbox URL.
Add a command to piem-dispatch that provides similar functionality.
