…BYTE_ARRAY as a standalone encong column encoding. java.lang.UnsupportedOperationException: Unsupported encoding: DELTA_LENGTH_BYTE_ARRAY Added additional test case to ParquetIOSuite based on the associated test file from https://github.com/apache/parquet-testing <!-- Thanks for sending a pull request!

Add DELTA_LENGTH_BYTE_ARRAY as a recognized encoding in VectorizedColumnReader so that vectorized reads succeed when there are columns using DELTA_LENGTH_BYTE_ARRAY as a standalone encoding. ### Why are the changes needed? Spark currently throws an exception for DELTA_LENGTH_BYTE_ARRAY columns when vectorized reads are enabled and trying to read `delta_length_byte_array.parquet` from https://github.com/apache/parquet-testing: java.lang.UnsupportedOperationException: Unsupported encoding: DELTA_LENGTH_BYTE_ARRAY ### Does this PR introduce _any_ user-facing change? Yes - previously throw UNSUPPORTED exception. Now reads the encoding same as if vectorized reads are disabled. ### How was this patch tested? Added test case to ParquetIOSuite; made sure it fails without the fix to VectorizedColumnReader and passes after. -- This is an automated message from the Apache Git Service.
