grumpy: Read 'NumPy' '.npy' and '.npz' Files

Lightweight way to read 'NumPy' '.npy' and '.npz' files in R. All data types supported by 'NumPy', with all sizes (converted internally to R native size), both C and 'Fortran' order, and any shape, up to an arbitrary number of dimensions, are supported.
