when you're resampling, you *always* need FIR filters. Can you confirm
your application really doesn't need them and that you have fully
understood the theory behind resampling?
The filter equivalent of a neutral element would be a Dirac impulse,
i.e. std::vector<float>(1, 1) (In Python notation: (1,) ).
I recommend you calculate suitable taps a-priori (say, using
gr_filter_design) and import them as a static vector into your code.
