Issue with "unicode" is not defied

[hjacquemin]

On line 330, I get an error while I run the script:

Traceback (most recent call last): File "./censys_io.py, line 330, in match = unicode(args.match) NameError: name 'unicode' is not defined

Same error depends on arguments used for line 403, 117. Probably lines 118-123, 149, 190 are also impacted.
