-/// - hl_eol : when true, for a multiline highlight covering the
-/// EOL of a line, continue the highlight for the rest
-/// of the screen line (just like for diff and
-/// cursorline highlight).
-/// - virt_text : virtual text to link to this mark.
-/// A list of [text, highlight] tuples, each representing a
-/// text chunk with specified highlight. `highlight` element
-/// can either be a a single highlight group, or an array of
-/// multiple highlight groups that will be stacked
-/// (highest priority last). A highlight group can be supplied
-/// either as a string or as an integer, the latter which
-/// can be obtained using |nvim_get_hl_id_by_name|.
-/// - virt_text_pos : position of virtual text. Possible values:
-/// - "eol": right after eol character (default)
-/// - "overlay": display over the specified column, without
-/// shifting the underlying text.
-/// - "right_align": display right aligned in the window.
-/// - virt_text_win_col : position the virtual text at a fixed
-/// window column (starting from the first
-/// text column)
-/// - virt_text_hide : hide the virtual text when the background
-/// text is selected or hidden due to
-/// horizontal scroll 'nowrap'
-/// - hl_mode : control how highlights are combined with the

-/// - "replace": only show the virt_text color. This is the
-/// default
-/// - "combine": combine with background text color
-/// - "blend": blend with background text color.
-///
-/// - virt_lines : virtual lines to add next to this mark
-/// This should be an array over lines, where each line in
-/// turn is an array over [text, highlight] tuples. In
-/// general, buffer and window options do not affect the
-/// display of the text. In particular 'wrap'
-/// and 'linebreak' options do not take effect, so
-/// the number of extra screen lines will always match
-/// the size of the array. However the 'tabstop' buffer
-/// option is still used for hard tabs. By default lines are
-/// placed below the buffer line containing the mark.
-///
-/// - virt_lines_above: place virtual lines above instead.
-/// - virt_lines_leftcol: Place extmarks in the leftmost
-/// column of the window, bypassing
-/// sign and number columns.
-///
-/// - ephemeral : for use with |nvim_set_decoration_provider|
-/// callbacks. The mark will only be used for the current
-/// redraw cycle, and not be permantently stored in the
-/// buffer.
-/// - right_gravity : boolean that indicates the direction
-/// the extmark will be shifted in when new text is inserted
-/// (true for right, false for left). defaults to true.
-/// - end_right_gravity : boolean that indicates the direction
-/// the extmark end position (if it exists) will be shifted
-/// in when new text is inserted (true for right, false
-/// for left). Defaults to false.
-/// - priority: a priority value for the highlight group. For
-/// example treesitter highlighting uses a value of 100.

-/// Adds a highlight to buffer.
