docs(aes,des): add crate documentation and improve re-exports 
Add crate-level doc comments with usage examples. Export additional
types for library users:
    - aes: Block32 (32-bit word type)
    - des: LR (Feistel round state)

docs(des): document Feistel network and cipher operations 
Add doc comments to LR struct and DES helper functions explaining the
Feistel network structure: IP -> 16 rounds -> FP, with each round using
expansion, S-box substitution, and P-box permutation.

docs(aes): document cipher operation functions 
Add doc comments explaining the four AES round operations:
    - SubBytes: S-box substitution for non-linearity
    - ShiftRows: cyclic row shifting for column diffusion
    - MixColumns: GF(2^8) matrix multiplication for row diffusion
    - AddRoundKey: XOR with derived subkey

docs(cipher-core): add documentation to public traits 
Document BlockCipher, InputBlock, and BlockParser with usage examples
and method descriptions. Fix incorrect error message in decrypt() that
referenced "plaintext" instead of "ciphertext".

refactor(cipher-core): unify secret_block! and secret_key! macros 
Move duplicated macro definitions from aes and des crates into
cipher-core for shared use. Both macros now:
    - Support u8 through u128 integer types
    - Include Zeroize derive for secure memory handling
    - Generate consistent formatting and conversion methods

refactor(cipher-core): extract shared block parsing logic 
Add generic BlockInt trait and parse_block_int<T>() function to
cipher-core, eliminating duplicate parsing code in aes and des crates.
    - BlockInt trait abstracts over u64/u128 integer types
    - Supports hex (0x), binary (0b), and ASCII string formats
    - Improved BlockError::InvalidByteStringLength with max/actual fields
