- removed pydc.py wrapper overhead (which only called pydcext.so functions, directly, anyways) * implies renaming pydcext.* to pydc.* * while at it, iterate directly over args that are passed in (before we did extract fptr, sig and a tuple for the args and iterated over latter afterwards); we might have a tiny perf improvement now - added type stub as package_data
