crypto-helper page: improve krb output: integrate `SimpleOutput` component

[TheBestTvarynka]

at the current moment, we use a custom output component for the output of the krb cipher: https://github.com/TheBestTvarynka/crypto-helper/blob/main/src/crypto_helper/output/krb.rs#L17

But it's obviously better to integrate the SimpleOutput (https://github.com/TheBestTvarynka/crypto-helper/blob/main/src/common/simple_output.rs) component into it. In such a way we'll be able to see output bytes in different representations
