Deprecate parquet-thrift

I was in the process of updating to [the latest version of Thrift](https://github.com/apache/parquet-mr/pull/1138) (from 0.16.0 to 0.19.0). Mostly because it contains CVEs and makes the release process easier because you don't have to install Thrift from source (it is just available on homebrew etc).
 
While working on this, I ran into an issue with Elephantbird, which is using a very old version of Thrift (0.7.0). Trying to bump this I noticed that a lot of classes that we use in the tests [have](https://github.com/apache/parquet-mr/pull/1156) [ been made private](https://github.com/apache/parquet-mr/pull/1156). Therefore it is hard to test if we break anything.
 
It looks like parquet-thrift [is not used by anyone anymore](https://mvnrepository.com/artifact/org.apache.parquet/parquet-thrift). I would suggest removing this from the repository unless anyone objects.

Beginne damit, das Modul parquet-thrift zu lokalisieren und seine Verwendungen im Repository zu prüfen. Lies anschließend die verlinkte Migrationsdokumentation und den zugehörigen Kontext zum Thrift-Upgrade. Erledigt ist die Aufgabe, wenn parquet-thrift aus dem Repository entfernt wurde, ohne die verbleibenden Module oder den dokumentierten Migrationspfad zu beeinträchtigen.
