    Adds @font-face support for fonts contained in package pymupdf-fonts.

    Creates a CSS font-family for all fonts starting with string 'fontcode'.

    Note:
        The font naming convention in package pymupdf-fonts is "fontcode<sf>",
        where the suffix "sf" is either empty or one of "it", "bo" or "bi".
        These suffixes thus represent the regular, italic, bold or bold-italic
        variants of a font. For example, font code "notos" refers to fonts
        "notos" - "Noto Sans Regular"
        "notosit" - "Noto Sans Italic"
        "notosbo" - "Noto Sans Bold"
        "notosbi" - "Noto Sans Bold Italic"

        This function creates four CSS @font-face definitions and collectively
        assigns the font-family name "notos" to them (or the "name" value).

    All fitting font buffers of the pymupdf-fonts package are placed / added
    to the archive provided as parameter.
    To use the font in fitz.Story, execute 'set_font(fontcode)'. The correct
    font weight (bold) or style (italic) will automatically be selected.
    Expects and returns the CSS source, with the new CSS definitions appended.

    Args:
        fontcode: (str) font code for naming the font variants to include.
                  E.g. "fig" adds notos, notosi, notosb, notosbi fonts.
                  A maximum of 4 font variants is accepted.
        CSS: (str) CSS string to add @font-face definitions to.
        archive: (Archive, mandatory) where to place the font buffers.
        name: (str) use this as family-name instead of 'fontcode'.
    Returns:
        Modified CSS, with appended @font-face statements for each font variant
        of fontcode.
        Fontbuffers associated with "fontcode" will be added to 'archive'.
