…t timeseries and chunk and pagereader.
… statistics is not valid when any type transfer to STRING/TEXT type. For example, when try to get max() value in the sql, will occur '512' > '1024', max() value is 512;
… "String", but not "Binary".
…e value two sides of assert validation ago.
…ismatched: class StringStatistics vs BinaryStatistics" when tsfile is unclosed and current type and previous type is not compatible.

Fix the problem that valueChunkMetadata get wrong datatype so that can't generate valid statistics object in the switch code block cause by newChunkMetadata set the property value of TsDataType
