feat: poseidon and pedersen extended benchmarks

[maciejka]

Add benchmarks for poseidon and pedersen hashes for both hash and hash_array functions. There are three benchmarks for each hash function:

• *_hash_single_input - same random pair of inputs is used for each hash function timing
• *_hash_multiple_inputs - different random pair of inputs is used for each hash function timing, probably gives more realistic measurements
• *_hash_array - for input lengths: 2, 4, 8, 16, different values are used for each hash_many timing
