Overhaul Python string creation and extraction * oct-py-types.cc, oct-py-types.h (pytave::extract_py_str, pytave::make_py_str): New functions to create a Python string and extract string value from Python. (pytave::make_py_dict): Use make_py_str. * octave_to_python.cc (pytave::octvalue_to_pyobj): Use make_py_str. (pytave::octstring_to_pyobject): Delete. * python_to_octave.cc (pytave::pyobj_to_octvalue): Use extract_py_str. (pytave::pyunicode_to_utf8): Delete.
