Encode binary file to printable utf16be, and vice versa.
It is a Rust reimplementation of base16384.
```rust use base16384::Base16384;
let data = b"12345678"; let encoded = Base16384::encode(data); let text = String::fromutf16(&encoded).unwrap(); asserteq!(text, "婌焳廔萷尀㴁"); ```
```rust use base16384::Base16384;
let data = "婌焳廔萷尀㴁".encodeutf16().collect::
