broadcast across multidimensional arrays.

* The ARTIQ compiler now implements arrays following NumPy semantics, rather than as a
thin veneer around lists. Most prior use cases of NumPy arrays in kernels should work
unchanged with the new implementation, but the behavior might differ slightly in some
cases (for instance, non-rectangular arrays are not currently supported).
