Bugfix/verify_required_parameters

[jack1902]

corrected verify_required_parameters so that it checks for all properties correctly, if a single property is missing, then it returns false immediately to log out the message from this if/else block:

if verify_required_properties(deep_security_event):
    forward_event = evaluate_deep_security_event(deep_security_event)
    if forward_event:
        print("Important security event detected, queuing to send to AWS Security Hub")
        aff_event = convert_deep_security_event_to_aff(deep_security_event)
        aff_events.append(aff_event)
        forwarded_events += 1
    else:
        print("Security event does not meet the criteria to send to AWS Security Hub")
else:
    print("Specified event does not have the required properties to properly process it")
