    ox-icalendar: Fix error dangling footnotes
    
    * lisp/ox-icalendar.el (icalendar): Add an inner-template function so
    as to not use "ox-ascii"'s.
    (org-icalendar-inner-template): New function.
    
    This fixes 
<https://lists.gnu.org/archive/html/emacs-orgmode/2013-04/msg01478.html>
    and <http://lists.gnu.org/r/emacs-orgmode/2021-11/msg00395.html>.
    
    Footnote definition is lost, but references are already removed from
    the description anyway, so the problem is not worse.
