Rust BIP47 Library

This library implements the BIP47 standard and provides functionality for generating static payment codes that two parties can use to create a private payment address space between them.

Original specification: BIP-0047.

Usage

```rust // Alice constructs her own payment code using a BIP32 seed let aliceprivate = PrivateCode::fromseed(&alice_seed, 0, Network::Bitcoin).unwrap();

// Alice parses Bob's payment code let bobpublic = PublicCode::fromwif("PM8TJS2JxQ5ztXUpBBRnpTbcUXbUHy2T1abfrb3KkAAtMEGNbey4oumH7Hc578WgQJhPjBxteQ5GHHToTYHE3A1w6p7tU6KSoFmWBVbFGjKPisZDbP97").unwrap();

// Alice calculates Bob's receive address at index 0, known only to them let bobaddress0 = bobpublic.address(&aliceprivate, 0, false).unwrap();

// Alice can now pay Bob privately asserteq!("12edoJAofkjCsWrtmVjuQgMUKJ6Z7Ntpzx", bobaddress0.tostring());

```
