* Fix blake2 binding Currently calling `hashlib.blake2b` results in the following type errors: Cannot instantiate abstract class '_BlakeHash' with abstract attributes 'copy', 'digest', 'hexdigest' and 'update' Missing positional arguments "data", "key", "salt", "person", "fanout", "depth", "leaf_size", "node_offset", "node_depth", "inner_size", "last_node" in call to "_BlakeHash" * Additional changes to reflect the hashlib implementation Modifies the type signatures of: * blake2b * blake2s * sha3_224 * sha3_256 * sha3_384 * sha3_512 * shake_128 * shake_256 To reflect the types that are implemented in the standard library. These should be exposed as `type`s instead of `builtin_function_or_method`s. e.g. In [40]: type(hashlib.blake2b) Out[40]: type In [41]: type(hashlib.md5) Out[41]: builtin_function_or_method
