Creates a stream kernel, without collision.
For parameters see function ``create_stream_pull_collide_kernel``
Args:
stencil: lattice Boltzmann stencil which is used
numpy_arr: numpy array which containes the pdf field data. If no numpy array is provided the symbolic field
accesses are created with
'
Field.create_generic
'
. Otherwise
'
Field.create_from_numpy_array

is used.
src_field_name: name of the source field.

generic_layout: data layout. for example
'

of
'

generic_field_type: field data type.
accessor: Field accessor which is used to create the update rule. See
