ADD: edf2py

- ctypes wrapper of C edfapi lib.
- pyeparse.edfapi.edf2pygen contains files for making the edfapi lib
cytpes wrapper. This is not needed when deploying.
- pyeparse.edfapi.edf2py contains the runtime files used, a Windows
edfapi.dll file, and an example (example.py) of where things are at /
tested.
- example.py is referencing the  tests/data/test_2_raw.edf

Change as you like. Comments / feedback is always great. Let me know if
I can help any further on this part.

Thanks.
