Review Comment:
This PR currently implements automatic fallback to aircompressor when
`zstd-jni` is unavailable, and also implements the configuration of
`orc.compression.zstd.impl=java` to force the use of aircompressor for writing.
However, there is currently no implementation of forcing the use of
aircompressor for reading. Because it is a bit difficult to pass configuration
items in the reader.
