Log Message:
(textproc/R-xml2) Updated 1.2.2 to 1.3.2

# xml2 1.3.2

* `read_html()` and `read_xml()` now error if passed strings of length
  greater than one (#121)

* `read_xml.raw()` had an inadvertent regression in 1.3.0 and is now
  again fixed (#300)

* Compilation fix on macOS 10.15.4 (@kevinushey, #296)

# xml2 1.3.1

* `read_html()` now again works with HTML files with non-ASCII encodings (#293).

# xml2 1.3.0

* Removes the Rcpp dependency

# xml2 1.2.5

* Fix compilation issue on macOS versions after High Sierra when not
  using homebrew supplied libxml2

# xml2 1.2.4

* Fix potential dangling pointer with internal `asXmlChar()` function
  (@michaelquinn32, #287).

* `as_xml_document()` now handles cases with text nodes trailing
  normal nodes (#274).

* `xml_add_child()` can now create nodes with a `par` attribute. These
  previously errored due to partial name matching of the `parent`
  function in the internal `create_node()` function. (@jennybc, #285)

* `libxml2_version()` now returns a semantic version rather than
  alphanumeric version, so "2.9.10" > "2.9.9" (#277)
