Use asarray in block_generate_dictionary_parallel
Use asarray in block_generate_dictionary_parallel

Instead of using `numpy.array`, use `numpy.asarray` in
`block_generate_dictionary_parallel`. This should make it faster when
actual NumPy arrays are involved. No change for cases where other arrays
that are convertible to NumPy are used.
