[NativeBinaryLoader] Allow loading natives via JME NativeLibraryLoader about jme-alloc

[Ali-RS]

What about using a system property? for example System.getProperty("com.jme3.alloc.librarypath")

NativeBinaryLoader can first check if the librarypath property is set and load it from there otherwise extract it automatically.

Edit:

Never mind, I think using NativeBinaryLoadr.setAutoLoad(false) is fine.

If you also cannot think of a good place to make a call for NativeBinaryLoadr.setAutoLoad(false), please let me know, too.

I think it should be in the class implementing JME BufferAllocator interface. (i.e. LwjglBufferAllocator).

    public class LwjglBufferAllocator implements BufferAllocator {

        static {
              NativeBinaryLoadr.setAutoLoad(false);
              NativeLibraryLoader.load(JmeAlloc);
        }

        @Override
        public void destroyDirectBuffer(Buffer toBeDestroyed) {
            NativeBufferAllocator.releaseDirectByteBuffer(toBeDestroyed);
        }

        @Override
        public ByteBuffer allocate(int size) {
            return NativeBufferAllocator.createDirectByteBuffer(size);
        }
    }

@Ali-RS Feel free to review PR #50.

This could be managed by creating a static Boolean flag NativeBinaryLoader.isAutoLoad() and it's setter method.

Notice, the flag should be true by default; because disabling the extraction process by default will break the test CI/CD workflow, so you will have to set this manually when implementing in jMonkeyEngine, before calling the NativeBufferAllocator.<cinit> (the static initializer).

If you agree on these modifications, please let me know, so I could prepare my schedule to solve this issue.
