Function multiply_frequency_response32 

#[unsafe(no_mangle)]
pub extern "C" fn multiply_frequency_response32(
    vector: Box<VecBuf>,
    frequency_response: i32,
    rolloff: f32,
    ratio: f32,
) -> VectorInteropResult<VecBuf>

frequency_response argument is translated to:

1. 0 to SincFunction
2. 1 to RaisedCosineFunction

rolloff is only used if this is a valid parameter for the selected frequency_response
