Upgrade dependencies to latest stable

zip 0.6.6 -> 8.6.0 (the 0.6 line is unmaintained), aes 0.8 -> 0.9
(BlockCipherDecrypt trait replaces BlockDecrypt), sha2 0.10 -> 0.11
(Array no longer formats as hex; local hex_digest helpers). Outputs are
byte-identical across the upgrade: full golden corpus and Android corpus
sidecars all pass.
