Summary description: Customize superscripts and subscripts

Announcement text:
----------------------------------------------------------------------


- Macro package options `text`, `math`, `foot` can be changed in the body, and styles corresponding to superscript and subscript `textsp`, `textsb`, `mathsp`, `mathsb`, `fnmark` were added.

- Added option `thiswd=(auto|keep)` and option `regex` to determine whether the current marker width is zero after using the super-subscript command based on whether the next command is the opposite super-subscript command.
