PARQUET-1998: Add LZ_RAW compressed files

The files were generated with Parquet C++.

* `lz4_raw_compressed.parquet` contains the same data as `hadoop_lz4_compressed.parquet`.
* `lz4_raw_compressed_larger.parquet` contains the same data as `hadoop_lz4_compressed_larger.parquet`.

Here are the file contents for `lz4_raw_compressed.parquet`:
