Created temporary valid pipeline to avoid long ce traces.
Correct valid pipe error.
Corrected CORDIC output.
Correct miscalculated valid_pipe length.
Added right-side padding inside cording, improving rounding error. This
parameter may be set using a generic in the cordic_core, but is
automatically set in the cordic_vectoring_slv.
Added wishbonized version of the vectoring module.
