Bech32 Rust

Rust implementation of the Bech32 encoding format described in BIP-0173.

Bitcoin-specific address encoding is handled by the bitcoin-bech32 crate.

Example

```rust use bech32::Bech32;

let b = Bech32 { hrp: "bech32".tostring(), data: vec![0x00, 0x01, 0x02] }; let encoded = b.tostring().unwrap(); asserteq!(encoded, "bech321qpz4nc4pe".tostring());

let c = Bech32::fromstring(encoded); asserteq!(b, c.unwrap()); ```
