Performance improvement
This release leverages improvements in JNA 5.12.0 which should significantly improve performance. Finalizers in JNA were replaced by Cleaners, reducing the impact of native memory allocations in tenured heap space by promptly releasing native memory allocations and reducing Garbage Collector usage.
JNA's Memory class now implements Closeable. All direct allocations of Memory and classes extending JNA's ByReference have their underlying Memory allocation freed proactively. Classes extending Structure on the hot path are also proactively freed.
