- update to 3.1.4:
  * Fix to type annotation that referenced `re.Pattern`. Since
    this type was introduced in Python 3.7, using this type
    definition broke Python 3.6 installs of pyparsing.
  * Added new `Tag` ParserElement, for inserting metadata into
    the parsed results.
    This allows a parser to add metadata or annotations to the
    parsed tokens.
  * The `Tag` element also accepts an optional `value`
    parameter, defaulting to `True`.
    See the new `tag_metadata.py` example in the `examples`
    directory.
  * Fixed issue where PEP8 compatibility names for
    `ParserElement` static methods were
    not themselves defined as `staticmethods`. When called
    using a `ParserElement` instance, this resulted  in a
   `TypeError` exception.
  * To address a compatibility issue in RDFLib, added a property
    setter for the `ParserElement.name` property, to call
    `ParserElement.set_name`.
  * Modified `ParserElement.set_name()` to accept a None value,
    to clear the defined name and corresponding error message for
    a `ParserElement`.
  * Updated railroad diagram generation for `ZeroOrMore` and
    `OneOrMore` expressions with `stop_on` expressions, while
    investigating #558
  * Added exception type to `trace_parse_action` exception
    output, while investigating SO question posted by medihack.
  * Added `set_name` calls to internal expressions generated in
    `infix_notation`, for improved railroad diagramming.
