private Options modifyForNonAcidSchemaRead(Options baseOptions, long writeId, Path rootPath) {

This is done to read non-acid schema files ("original") located in base_x/ or delta_x_x/ which
happens as a result of Load Data statement.  Setting {@code rootPath} to base_x/ or delta_x_x
causes {@link AcidUtils#getAcidState(Path, Configuration, ValidWriteIdList)} in subsequent
{@link OriginalReaderPair} object to return the files in this dir
in {@link AcidDirectory#getOriginalFiles()}
@return modified clone of {@code baseOptions}
