Add TreeHasher to simplify currying puzzle hashes

[Rigidity]

Instead of having to special case untyped currying code with curry_tree_hash for each puzzle type, you can use CurriedProgram directly now. Here is an example:

let puzzle_hash = CurriedProgram {
    program: CAT_PUZZLE_HASH,
    args: CatArgs {
        mod_hash: CAT_PUZZLE_HASH.into(),
        tail_program_hash: CurriedProgram {
            program: GENESIS_BY_COIN_ID_TAIL_PUZZLE_HASH,
            args: GenesisByCoinIdTailArgs {
                genesis_coin_id: Bytes32::default(),
            },
        }
        .tree_hash()
        .into(),
        inner_puzzle: CurriedProgram {
            program: STANDARD_PUZZLE_HASH,
            args: StandardArgs {
                synthetic_key: PublicKey::default(),
            },
        },
    },
}
.tree_hash();
