Impulse is the basic source primitive PTransformClass. It receives a Beam
Root as input, and returns a PCollection of Uint8Array with a single
element with length=0 (i.e. the empty byte array: new Uint8Array("")).
Impulse is used to start the execution of a pipeline with a single element
that can trigger execution of a source or SDF.
