Add "stateful" feature type with initial feature "last n"

Stateful feature extraction functions are functions that require state to be maintained between successive calls.  This is necessary, for example when an accumulation of values is required, or changes need to be measured over time.

The initial xtract_last_n() function accumulates the last N (single) values from *data and writes them to *result

# SYNOPSIS
#
#   AX_SWIG_PYTHON([use-shadow-classes = {no, yes}])
#
# DESCRIPTION
#
#   Checks for Python and provides the $(AX_SWIG_PYTHON_CPPFLAGS), and
#   $(AX_SWIG_PYTHON_OPT) output variables.
#
#   $(AX_SWIG_PYTHON_OPT) contains all necessary SWIG options to generate
#   code for Python. Shadow classes are enabled unless the value of the
#   optional first argument is exactly 'no'. If you need multi module
#   support (provided by the AX_SWIG_MULTI_MODULE_SUPPORT macro) use
#   $(AX_SWIG_PYTHON_LIBS) to link against the appropriate library. It
#   contains the SWIG Python runtime library that is needed by the type
#   check system for example.
