Respect Org Mode variables for controlling sub/superscripts

+- ~org-pretty-entities-include-sub-superscripts~ :: Whether to prettify

+- ~org-use-sub-superscripts~ :: When subscripts and superscripts are enabled,

 - ~org-hide-emphasis-markers~ :: Whether to hide emphasis markers. Emphasis
   markers are hidden in [[*Reader Mode][Reader Mode]], but this allows hiding them outside of
   Reader Mode as well.
