-A file in NPY format.
-
-Currently unsupported types:
-
-* unsigned integral types (treated as signed)
-* bit field,
-* complex,
-* object,
-* Unicode
-* void*
-* intersections aka types for structured arrays.
-
-See http://docs.scipy.org/doc/numpy-dev/neps/npy-format.html
-
-Example:
-
-``` kotlin
-val values = intArrayOf(1, 2, 3, 4, 5, 6)
-val path = Paths.get("sample.npy")
-NpyFile.write(path, values, shape = intArrayOf(2, 3))
-println(NpyFile.read(path))
-// =&gt; NpyArray{data=[1, 2, 3, 4, 5, 6], shape=[2, 3]}

+A writer for NPZ format.

+requires N extra bytes of memory for an array of N bytes.
