AIngle base32 encoding scheme for keys, agents, identifiers, etc.
```rust extern crate aiid;
fn main() { let enc = aiid::aiidEncoding::withkind("ais0").unwrap(); let key = enc.encode(&[0; 32]).unwrap(); asserteq!("aiSciaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa", key); let buffer = enc.decode(&key).unwrap(); asserteq!([0; 32].tovec(), buffer); } ```
