tiny dollnary implementation
example:
use dollnary;
let encoded = dollnary::encode(0x464383c);
assert_eq!(encoded, String::from("││╽│╽╿╽││┃╿││┃┃│"));
// decoding can fail if the input isn't well-formatted, so it returns an Option
let decoded = dollnary::decode(&encoded);
assert_eq!(decoded, Some(0x464383c));
assert_eq!(dollnary::decode("invalid"), None);
