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

Inizia tracciando l’avvio di parquet-tools attorno alle sostituzioni di System.setOut(System.setErr), a VoidStream e al percorso die() che segnala a Main.err. Riproduci l’invocazione diretta di java -jar senza il prefisso hadoop e confrontala con il comportamento dopo che questi stream non sopprimono più gli errori. Il lavoro è completato quando i fallimenti dovuti a classi mancanti vengono segnalati invece di non produrre alcun output.
