docs: python bindings and its special request

* Added some material on using the new-ish hkp4py module with GPGME.
* Example code will be added later once a couple of little issues are
  addressed.

+
+The [[https://github.com/Selfnet/hkp4py][hkp4py]] module by Marcel Fest was originally a port of the old
+[[https://github.com/dgladkov/python-hkp][python-hkp]] module from Python 2 to Python 3 and updated to use the
+[[http://docs.python-requests.org/en/latest/index.html][requests]] module instead.  It has since been modified to provide
+support for Python 2.7 as well and is available via PyPI.
+
+Since it rewrites the =hkp= protocol prefix as =http= and =hkps= as
+=https=, the module is able to be used even with servers which do not
+support the full scope of keyserver functions.  It will work quite
+readily when incorporated into a [[#cython][Cython]] generated and compiled version

+The hkp4py module returns key data via requests as string literals
+(=r.text=) instead of byte literals (=r.content=).  This means that
+the retrurned key data must be encoded to UTF-8 when importing that
+key material using a =gpg.Context().key_import()= method.
