v1.6.1

Consumer/Producer config can now be provided with a sym list as a configuration value. As as example, see metadata.broker.list in the following config

kfk_cfg:(!) . flip(
    (`group.id;`0);
    (`metadata.broker.list;`localhost:9092`localhost:9091);
    (`fetch.wait.max.ms;`10);
    (`auto.offset.reset;`earliest);
    (`enable.auto.commit;`false);
    (`statistics.interval.ms;`10000)
    );

Previous releases could give an erroneous error when provided with this type.
