Class PeerMap<T>

We can't use PeerIds as map keys because map keys are compared using same-value-zero equality, so this is just a map that stringifies the PeerIds before storing them.

PeerIds cache stringified versions of themselves so this should be a cheap operation.

Example

import { peerMap } from '@libp2p/peer-collections'

const map = peerMap<string>()
map.set(peerId, 'value')
