The purpose of this branch is to reimplement Keccak algorithm based on the pointycastle library. This addition enables secure hashing and is essential for supporting Ethereum-related operations, such as transaction validation and signing. List of changes: - created keccak.dart to simplify data absorption, finalization, and output generation using the Keccak sponge construction. This cryptographic algorithm absorbs an arbitrary-length input into an internal state and squeezes out a fixed-length output. Works by iteratively applying a permutation function through controlled input-output mixing. - created keccakf1600.dart to perform transformations on the 1600-bit state, achieving diffusion and mixing of bits across the state - created register64.dart and register64_list.dart to manage the 64-bit lanes and the state matrix of the algorithm
