Meant to be called from a module. `data` is a table containing the following fields:

{
  lang = LANGUAGE_OBJECT,
  hyphs = {{hyph = {"SYL", "SYL", ...}, qualifiers = nil or {"QUALIFIER", "QUALIFIER", ...}}, ...},
  sc = nil or SCRIPT_OBJECT,
  caption = nil or "CAPTION",
  nocaption = BOOLEAN,
}

Here:

* `lang` is a language object.
* `hyphs` is the list of hyphenations to display. SYL is a syllable. QUALIFIER is a qualifier string to display before
  the specific hyphenation in question, formatted using format_qualifier() in [[Module:qualifier]].
* `sc`, if specified, is a script object.
* `caption`, if specified, overrides the default caption "Hyphenation". A colon and space is automatically added after
  the caption.
* `nocaption`, if specified, suppresses the caption entirely.
