FFTW preset, fftwf_iodim and fftwf_iodim64 missing array allocators

[hageldave]

Hello, I previously reported missing definitions of fftw_iodim struct in #466 which was already fixed.
Now I just noticed that the float version of this class does not provide the same interface.

Here is the definition of fftw_iodim:

@Name("fftw_iodim_do_not_use_me") public static class fftw_iodim extends Pointer {
    static { Loader.load(); }
    /** Default native constructor. */
    public fftw_iodim() { super((Pointer)null); allocate(); }
    /** Native array allocator. Access with {@link Pointer#position(long)}. */
    public fftw_iodim(long size) { super((Pointer)null); allocateArray(size); }
    /** Pointer cast constructor. Invokes {@link Pointer#Pointer(Pointer)}. */
    public fftw_iodim(Pointer p) { super(p); }
    private native void allocate();
    private native void allocateArray(long size);
    @Override public fftw_iodim position(long position) {
        return (fftw_iodim)super.position(position);
    }

     public native int n(); public native fftw_iodim n(int n);                     /* dimension size */
     public native int is(); public native fftw_iodim is(int is);			/* input stride */
     public native int os(); public native fftw_iodim os(int os);			/* output stride */
}

and here the definition of fftwf_iodim:

@Opaque public static class fftwf_iodim extends Pointer {
    /** Empty constructor. Calls {@code super((Pointer)null)}. */
    public fftwf_iodim() { super((Pointer)null); }
    /** Pointer cast constructor. Invokes {@link Pointer#Pointer(Pointer)}. */
    public fftwf_iodim(Pointer p) { super(p); }
}

I think there's something missing but I could be wrong and maybe there is another way of using the fftwf_iodim class to allocate an array of it and set n, is, os.

Yes, they are missing, but they are just typedefs of the same struct. I'll make the necessary changes later today. Thanks for reporting!

For now, we can do something like this:

fftw_iodim dims = new fftw_iodim(n);
// ...
fftwf_iodim fdims = new fftwf_iodim(dims);

nice, pretty fast support on here :)

FYI, released with version 1.4.1. Enjoy!
