Vectorized evaluator of cipher_partial_inverse is not working

[juaninf]

The following portion of code related to the vectorized evaluation of the inverse of last round of SpeckBlockCipher is not working. Even uncommenting the commented lines (due #337).

from claasp.ciphers.block_ciphers.speck_block_cipher import SpeckBlockCipher
import numpy as np

speck_cipher = SpeckBlockCipher(number_of_rounds=5)
speck_cipher_without_key_schedule = speck_cipher.remove_key_schedule()
partial_speck = speck_cipher_without_key_schedule.cipher_partial_inverse(4, 4, True)
#partial_speck.set_inputs(['cipher_output_4_12', 'key_4_2'], [32, 16])
#partial_speck.get_all_components()[-1]._description[0] = "cipher_output"
#del partial_speck._rounds.rounds[3]
#del partial_speck._rounds.rounds[2]
#del partial_speck._rounds.rounds[1]
#partial_speck._rounds.rounds[1]._id = 1
rng = np.random.default_rng(10)
plaintext = rng.integers(low=0, high=256, size=(4, 1), dtype=np.uint8)
key = rng.integers(low=0, high=256, size=(2, 1), dtype=np.uint8)
partial_speck.evaluate_vectorized([plaintext, key])

The error is
