Investigate Apache Arrow usage for the PDAL <-> JVM interaction

[pomadchin]

Probably we can use Apache Arrow to simplify interaction between Java / C++ / Python / etc, however this requires some investigations.

• JMH Benchmarks that compare JVM Arrow to Java Collections
• Prototype an example that works in Arrow (bindings API)
• Benchmark the prototype

The next steps for this tasks would be:

1. to pack all the points taken from the pipeline into an apache arrow table
2. pass this into the JVM memory

NOTE: this experiment could be also a good test for the potential Python improvements as well, and mb it would be easier to exposer an Arrow table into Python rather than constructing a PyArray.
