Generate, import, and export PeerIDs.

A Peer ID is the SHA-256 [multihash](https://github.com/multiformats/multihash) of a public key.

The public key is a base64 encoded string of a protobuf containing an RSA DER buffer. This uses a node buffer to pass the base64 encoded public key protobuf to the multihash for ID generation.

## Example

```TypeScript
import { createEd25519PeerId } from '@libp2p/peer-id-factory'

const peerId = await createEd25519PeerId()
console.log(peerId.toString())
```

```bash
