 * Header/Footer Formatting Syntax taken from Office Open XML Part 4 - Markup Language Reference, page 1970:
 *
 * There are a number of formatting codes that can be written inline with the actual header / footer text, which
 * affect the formatting in the header or footer.
 *
 * Example: This example shows the text "Center Bold Header" on the first line (center section), and the date on
 * the second line (center section).
 *         &CCenter &"-,Bold"Bold&"-,Regular"Header_x000A_&D
 *
 * General Rules:
 * There is no required order in which these codes must appear.
 *
 * The first occurrence of the following codes turns the formatting ON, the second occurrence turns it OFF again:
 * - strikethrough
 * - superscript
 * - subscript
 * Superscript and subscript cannot both be ON at same time. Whichever comes first wins and the other is ignored,
 * while the first is ON.
 * &L - code for "left section" (there are three header / footer locations, "left", "center", and "right"). When
 * two or more occurrences of this section marker exist, the contents from all markers are concatenated, in the
 * order of appearance, and placed into the left section.
 * &P - code for "current page #"
 * &N - code for "total pages"
 * &font size - code for "text font size", where font size is a font size in points.
 * &K - code for "text font color"
 * RGB Color is specified as RRGGBB
 * Theme Color is specifed as TTSNN where TT is the theme color Id, S is either "+" or "-" of the tint/s...
