Description
https://xtensor-zarr.readthedocs.io/en/latest/basic_usage.html and https://github.com/xtensor-stack/xtensor-zarr/blob/master/README.md#usage are in sync with each other, but in significant dissonance with the code. Create an array example fails to compile with:
9>itkOMEZarrNGFFImageIOTest.cxx

And an attempt to modify it to work:
{
// create a hierarchy on the local file system
xt::xzarr_file_system_store store("test.zr3");
auto h = xt::create_zarr_hierarchy(store);
// create an array in the hierarchy
nlohmann::json attrs = { {"question", "life"}, {"answer", 42} };
using S = std::vector<std::size_t>;
S shape = { 4, 4 };
S chunk_shape = { 2, 2 };
xt::zarray a = h.create_array(
"/arthur/dent", // path to the array in the store
shape, // array shape
chunk_shape, // chunk shape
"<f8" // data type, here little-endian 64-bit floating point
);
// write array data
a(2, 1) = 3.;
}results in C:\Dev\ITKIOOMEZarrNGFF\test\itkOMEZarrNGFFImageIOTest.cxx(60,5): error C2064: term does not evaluate to a function taking 2 arguments at line a(2, 1) = 3.;.
