Explicit dependencies in pxf-hdfs (#60)

`parquet-pig` transitively pulls couple compressors to testRuntimeClasspath and hides the fact that pxf-hdfs doesn't have snappy, zstd as direct runtime dependency.

```
+--- org.apache.parquet:parquet-pig -> 1.15.2
    +--- org.apache.parquet:parquet-hadoop -> 1.15.2
    |    +--- org.apache.parquet:parquet-column:1.15.2 (*)
    |    +--- org.apache.parquet:parquet-format-structures:1.15.2 (*)
    |    +--- org.apache.parquet:parquet-common:1.15.2 (*)
    |    +--- org.apache.parquet:parquet-jackson:1.15.2
    |    +--- org.xerial.snappy:snappy-java:1.1.10.7
    |    +--- io.airlift:aircompressor:2.0.2
    |    +--- commons-pool:commons-pool:1.6
    |    +--- com.github.luben:zstd-jni:1.5.6-6 -> 1.5.7-6
    |    \--- org.slf4j:slf4j-api:1.7.33 -> 1.7.36
```

So, this PR removes transitive test-dependencies and explicitly adds runtime dependencies
