PN code sequential search correlator.
Receives complex baseband signal, outputs complex correlation against reference PN code, one sample per PN code period. The PN sequence is generated using a GLFSR.

degree | Degree of shift register must be in [1, 32]. If mask is 0, the degree determines a default mask (see digital_impl_glfsr.cc for the mapping). |
mask | Allows a user-defined bit mask for indexes of the shift register to feed back. |
seed | Initial setting for values in shift register. |
