start/end timezone issue

[SHSauler]

Dates miss tzinfo just by providing %Y-%m-%d and error gets raised:

    raise ValueError('%s.tzinfo must not be None!' % varname)

Fixed it with

import pytz
[...]
poll_from = datetime.strptime(args.start, "%Y-%m-%d%Z").replace(tzinfo=pytz.utc)

But then only UTC can be selected. Would this be okay? Then I'll submit this as PR.

Kind regards!

Added --tz option in 5233759

e.g

python3 scripts/run-taxii-poll.py -s --tz Europe/London

Defaults to UTC if not provided
