  1. Reimplements np_dot. There is no improvement on the types of ndarrays np_dot can handle. It is still limited to 1D 'dot' 1D and scalar 'dot' scalar.
  2. Adds general matrix multiplication.
    • 1D @ 2D, 2D @ 1D, and stacking are now supported.
    • Solves #397 (ndarray 1D matrix multiplication).

Other notes

On matmul's signature: Is the typechecker type correct? I have also encountered the same issue like np_size() when the other_ty of impl_matmul is simply set to [ndarray_unsized_t] - primitives.ndarray's dtype and ndims are substituted permanently. See commit "core/ndstrides: implement general matmul".
