Strict projection for dates timestamps

Expected behaviour: `ts > 2019-07-07T23:59:59.9999` can be projected strict using `ts_day` >= 2019-07-08
But for `ts > 2019-07-07T15:46:37.89789`, `ts_day` >= `2019-07-08` will only return a subset of the records (not returning records between 15th hour and last hour of 2019-07-07), so it cannot be a strict projection based on https://github.com/apache/incubator-iceberg/blob/master/api/src/main/java/org/apache/iceberg/expressions/ResidualEvaluator.java#L203
