Setup.py fails on windows because Readme.md is in utf-8

[rxm7706]

While running setup.py on windows I ran into an error
https://stackoverflow.com/questions/9233027/unicodedecodeerror-charmap-codec-cant-decode-byte-x-in-position-y-character
caused by

synthetic-data/setup.py

Line 27 in 0961953

long_description = readme.read()

The 'README.md' is in UTF-8 encoding and to get around this I believe
changing
with open('README.md', 'r') as readme:
to
with open('README.md', mode='r', encoding='utf8') as readme:

should fix the issue
