We allow to pass byte slices with lower length than the one indicated by the modulus of prime field. To ensure that it works, provide a test which compares that hashes produced from smaller inputs are equivalent to hashes produces from bigger inputs, filled up with zeros. Such inputs with different sizes are still representing the same prime field elements.

That new release contains an important change which prevents a potential DDoS. * Lightprotocol/light-poseidon#32 Invoking `from_bytes_be` function light-poseidon 0.1.1 inverts all the inputs before performing a check whether their length exceeds the modulus of the prime field. Therefore, it was prone to an attack, where a mailicious user could submit long byte slices just to DDoS the validator, being stuck on inverting large byte sequences. The update and mentioned change fixes the same issue as #33363 aims to address. The new release contains also few other less important changes like: * Lightprotocol/light-poseidon#37 * Lightprotocol/light-poseidon#38 * Lightprotocol/light-poseidon#39
