Do not read timestamps for blocks, which cannot contain surrounding logs. This should improve peformance for https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6730 . Also optimize min(_time) and max(_time) calculations a bit by avoiding conversion of timestamp to string when it isn't needed. This should improve performance for https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7070 .
