Add new functions to pack and unpack C double (serialize and deserialize): * PyFloat_Pack2(), PyFloat_Pack4(), PyFloat_Pack8() * PyFloat_Unpack2(), PyFloat_Unpack4(), PyFloat_Unpack8() Document these functions and add unit tests. Rename private functions and move them from the internal C API to the public C API: * _PyFloat_Pack2() => PyFloat_Pack2() * _PyFloat_Pack4() => PyFloat_Pack4() * _PyFloat_Pack8() => PyFloat_Pack8() * _PyFloat_Unpack2() => PyFloat_Unpack2() * _PyFloat_Unpack4() => PyFloat_Unpack4() * _PyFloat_Unpack8() => PyFloat_Unpack8() Replace the "unsigned char*" type with "char*" which is more common and easy to use.
