Encode and Decode Strings

Implement `encode(strings)` and `decode(text)` so that `decode(encode(xs)) == xs` for any list of strings, including empty strings and strings containing any character at all. encode(["hi", "there"]) -> some single string decode(that string) -> ["hi", "there"] Any delimiter you choose can appear inside the data. That is the whole question, and the answer is framing: write each string's length, then a marker, then the bytes — so the decoder never has to guess where a string ends.
