> Fallback support to pure Java compression

> Airlift’s aircompressor
> (https://search.maven.org/artifact/io.airlift/aircompressor) is an Apache 2
> licensed library, for Java 8 and up, available in Maven central, which
> provides pure Java implementations of gzip, lz4, lzo, snappy, and zstd and
> Hadoop compression codecs for same, claiming “_they are typically 300% faster
> than the JNI wrappers_.” (https://github.com/airlift/aircompressor). This
> library is under active development and up to date releases because it is
> used by Trino.
> Proposed changes:
> * Modify Compression.java such that compression codec implementation classes
> can be specified by configuration. Currently they are hardcoded as strings.
> * Pull in aircompressor as a ‘compile’ time dependency so it will be bundled
> into our build and made available on the server classpath.
> * Modify Compression.java to fall back to an aircompressor pure Java
> implementation if schema specifies a compression algorithm, a Hadoop native
> codec was specified as desired implementation, but the requisite native
> support is somehow not available.
