Base58 (Bitcoin alphabet) codec — Encode, Decode, IsValid, Alphabet.

Pure byte-slice math (the classic div/mod-by-58 carry loop), no math/big; leading zero bytes ↔ leading 1s. Ported from mr-tron/base58 / btcutil/base58.

4b := b58.Decode(s)                // []byte("hello") (nil if s has a non-alphabet char)
