[Java] Experiment with performance difference of avoiding the use of Avro Decoder

It has been posited that the Decoder object (and on-heap work in general) is potentially slow for decoding.

The scope of this Jira is to add a new method that instead of consuming from Decoder, consumes directly from a ByteBuffer.  In order to this we there needs to be utility classes for zig-zag decoding (one might existing in avro) from a ByteBuffer.

This is esentially rewriting logic in the decoder to work directly against a bytebuffer and then measure if there is a meaningful performance impact.

Beginne damit, den Java-Avro-Konvertierungscode zu finden, der Decoder verwendet, und überprüfe alle vorhandenen Avro-Hilfsfunktionen zur Zig-Zag-Decodierung. Die Arbeit ist abgeschlossen, wenn die auf ByteBuffer basierende Decodierung und ihre Hilfsfunktionen implementiert sind und Messungen zeigen, ob das Vermeiden von Decoder und Heap-Arbeit einen signifikanten Leistungseffekt hat.
