TransCompressionCommand Inoperable

`TransCompressionCommand` in parquet-tools is intended to allow translation of compression types in parquet files.  We are intending to use this functionality to debug a corrupted file, but this command fails to run at the moment entirely. 

Running the following command (on the uncorrupted file):
```java

java -jar ./parquet-tools-1.11.1.jar trans-compression ~/Downloads/part-00048-69f65188-94b5-4772-8906-5c78989240b5_00048.c000.snappy.parquet
```
This results in 

 
```java

Unknown command: trans-compression
```
 

I believe this is due to the Registry class [silently catching any errors to initialize](https://github.com/apache/parquet-mr/blob/master/parquet-tools/src/main/java/org/apache/parquet/tools/command/Registry.java#L65) which subsequently is [misinterpreted as an unknown command](https://github.com/apache/parquet-mr/blob/master/parquet-tools/src/main/java/org/apache/parquet/tools/Main.java#L200).

We need to: 
1. Write a test for the TransCompressionCommand to figure out why it's showing up as unknown command
1. Probably expand these tests to cover all the other commands

 

This will then unblock our debugging work on the suspect file. 

**Environment**: I am using parquet-tools 1.11.1 on a Mac machine running Catalina, and my parquet-tools jar was downloaded from Maven Central.

Comienza en parquet-tools/src/main/java/org/apache/parquet/tools/command/Registry.java y org/apache/parquet/tools/Main.java, y luego ejecuta el comando trans-compression indicado para reproducir el resultado unknown-command. Añade una prueba para TransCompressionCommand y amplía la cobertura a los demás comandos si corresponde; se considerará terminado cuando se reconozca el comando y las pruebas expliquen por qué fallaba anteriormente.
