Parse left and right regular and accent qualifiers and references, for pronunciation or related modules that want to
provide support for these.

`data` is a structure containing the following fields:
* `obj`: The object to write the parsed qualifiers and references into.
* `q`: Left regular qualifier.
* `qq`: Right regular qualifiers.
* `qualifiers`: Regular qualifiers (left or right), for compatibility.
* `a`: List of comma-separated left accent qualifiers.
* `aa`: List of right accent qualifiers, each a string.
* `refs: Spec for one or more references; see the documentation of [[Module:IPA]].

This function is used by any module that wants to add support for left and right regular and accent qualifiers to a
template that specifies a pronunciation or related property. It is currently used by [[Module:rhymes]],
[[Module:hyphenation]], [[Module:homophones]] and [[Module:es-pronunc]] (for specifying pronunciation, rhymes,
hyphenation, homophones and audio in {{tl|es-pr}}). It should potentially also be used in {{tl|audio}}. To reduce memory
usage, the caller should check that any qualifiers exist before loading the module.

`data` is a structure containing the following fields:
* `q`: List of left regular qualifiers, each a string.
* `qq`: List of right regular qualifiers, each a string.
* `qualifiers`: List of qualifiers, each a string, for compatibility. If `qualifiers_right` is given, these are
   right qualifiers, otherwise left qualifiers. If both `qualifiers` and `q`/`qq` (depending on the value of
   `qualifiers_right`) are non-{nil}, `qualifiers` is ignored.
* `a`: List of left accent qualifiers, each a string.
* `aa`: List of right accent qualifiers, each a string.
* `refs`: {nil} or a list of references or reference specs to add directly after the text; the value of a list item
  is either a string containing the reference text (typically a call to a citation template such as {{tl|cite-book}}, or
  a template wrapping such a call), or an object with fields `text` (the reference text), `name` (the name of the
  reference, as in {{cd|<nowiki><ref name="foo">...</ref></nowiki>}} or {{cd|<nowiki><ref name="foo" /></nowiki>}})
  and/or `group` (the group of the reference, as in {{cd|<nowiki><ref name="foo" group="bar">...</ref></nowiki>}} or
  {{cd|<nowiki><ref name="foo" group="bar"/></nowiki>}}); this uses a parser function to format the reference
  appropriately and insert a footnote number that hyperlinks to the actual reference, located in the
  {{cd|<nowiki><references /></nowiki>}} section.
* `lang`: Language object for accent qualifiers.
* `text`: The text to wrap with qualifiers.
* `qualifiers_right`: If specified, qualifiers in `qualifiers` are placed to the right, otherwise the left. See above.

Accent qualifiers precede (are to the left of) regular qualifiers, both on the left and right sides.
