Summary:
Change the tokenizer APIs to:

Result<std::vector<uint64_t>> encode(const std::string& input, int8_t bos, int8_t eos);
Result<std::string> decode(uint64_t prev_token, uint64_t token);

Notice that: we use uint64_t for token id just to be safe. We return a std::vector of tokens for encode() API.
