Description

closes: #494

On my local laptop (M1 pro), with payload size 1 << 25, payload_chunk_size = 256 and num_storage_nodes = 512.
Running with RAYON_NUM_THREADS=8.

Previous result for polynomial evaluation:

··Start:   encode payload bytes into polynomials
··End:     encode payload bytes into polynomials ...................................899.311ms
··Start:   compute all storage node evals for 4229 polynomials with 256 coefficients
··End:     compute all storage node evals for 4229 polynomials with 256 coefficients 1.026s

Now we have:
