parquet-tools class-not-found failures are silent and therefore not helpful

If you download a parquet-tools jar from e.g. maven central and simply run it without the "hadoop" command prefix:

`[jlilley@rpb-dev-cent7-1 ~]$ wget [https://repo1.maven.org/maven2/org/apache/parquet/parquet-tools/1.11.1/parquet-tools-1.11.1.jar]`
`...`

`[jlilley@rpb-dev-cent7-1 ~]$ java -jar parquet-tools-1.11.1.jar --help`
`[jlilley@rpb-dev-cent7-1 ~]$`

it will fail because the hadoop dependencies are missing, and will fail silently because System.out and System.err have been replaced with VoidStream:

`System.setOut(VoidStream);`
`System.setErr(VoidStream);`

Because of this, the missing-class exceptions are not reported and user is left scratching head and wondering what happened.  It is unclear why the message goes unreported, because the exception _should_ be printed to Main.err by die()

catch (Throwable th) {
`   if (debug) th.printStackTrace(Main.err);`
`   die(th, false, name, command);`
}

However, commenting out the System.setOut() and System.setErr() lines does indeed cause the stack trace to be shown.

**Environment**: I've tried this on both CentOS7 and Windows 10, using JDK 1.8.0_211

Comienza rastreando el inicio de parquet-tools en torno a las sustituciones de System.setOut(System.setErr), VoidStream y la ruta die() que informa a Main.err. Reproduce la invocación directa de java -jar sin el prefijo hadoop y compárala con el comportamiento después de que esos streams dejen de suprimir los errores. La tarea está completada cuando los fallos por clases ausentes se informan en lugar de no producir ninguna salida.
