The output signature for COMPLEX_INT16 is a vector of shorts length 2.
You can covert this to complex float with a vector_to_stream block, and
then a ishort_to_complex block.
BTW, if you want complex floats, it makes way more sense to just use
COMPLEX_FLOAT32. The real use of COMPLEX_INT16 is if you have a block
that produces or consumes complex shorts. Otherwise its just extra overhead.
