Please describe the bug 🐞

DataTypeChecks.isSupportedStatisticsType lists CHAR, so a table can enable statistics on a CHAR column and LogRecordBatchStatisticsCollector gives it an index slot and a null count. But the switch in updateMinMax (LogRecordBatchStatisticsCollector.java:134) has no CHAR case, so it falls through to the default branch and ships null bounds, leaving a filter on that column unable to prune anything.
