/**
 * Contains Panama and native SIMD implementations of various vector operations.
 * <p>
 * The native code is contained in C++ files, with implementations for ARM and two generations of x86,
 * using significant amounts of CPU intrinsics to utilise specific SIMD operations.
 * The method handles are loaded using FFI, and made available through a series
 * of wrapper classes to be called from Elasticsearch-defined vector formats.
 * <p>
 * Because the APIs used to perform SIMD operations from Java
 * and call native code changes between JVM versions,
 * there are different implementations of the wrapper classes for different JVM versions.
 * This is handled using multi-release jars, with the JVM-specific implementations
 * contained in the {@code mainXX} source sets.
 * <p>
 * As a result, some of the implementations in the {@code main} source set are not actually
 * called at runtime, and only exist to be compiled against. The correct implementation to use
 * at runtime is selected by the multi-release classloader.
