Hadamard product of TT batch and TT tensor

[KhrulkovV]

The following code fails a = t3f.random_tensor((3, 3, 3), tt_rank=2) b = t3f.random_tensor_batch((3, 3, 3), tt_rank=2, batch_size=5) t3f.multiply(a, b) with error ValueError: The arguments should have the same shape., but should be possible via broadcasting

t3f.multiply(b, b) also produces error
