Potential Panic on Overlong Ciphertext Buffer

An application that passes in a ciphertext buffer of length greater than ptxt.len + TAGLEN to libcruxchacha20poly1305::encrypt or libcruxchacha20poly1305::xchacha20poly1305::encrypt would experience a panic. Impact An application where the length of the ciphertext buffer is under attacker control...
