`-banned` and `-locked` are not respected when exposure file is used

[sharkiteuthis]

see here:

def run(league, args, existing_rosters=None, exposure_bounds=None):
    if exposure_bounds:
        exposure_args = get_exposure_args(...)
        args.locked = exposure_args['locked']
        args.banned = exposure_args['banned']

This might be resolved when you pip-ify the module for #63 and get away from the namespace stuff.
