normalize_csv.py
This script reads csv content from stdin, transforms that content, and prints the resulting csv back to stdout.
The script assumes the content on stdin will follow the format of sample.csv.
In the case of unicode decoding issues in timestamp, zipcode, fooduration, barduration, name, or address the row will be dropped and an error message printed to stderr

To run:
using python 3.6, install packages from requirements.txt

usage:
$ python normalize_csv.py < sample.csv

Some improvements would include:

• wraping parse code in _main_
• unit tests
• exception handling
