Error [ERR_SOCKET_DGRAM_NOT_RUNNING]: Not running

Hi, I'm getting this error trying to use the PMP client.

import { upnpNat, pmpNat } from '@achingbrain/nat-port-mapper'

async function main() {

//    const client = await upnpNat({
    const client = await pmpNat({
        // all fields are optional
        ttl: 20*60, // how long mappings should live for in seconds - min 20 minutes, default 2 hours
        description: 'hello', // default description to pass to the router for a mapped port
        gateway: '10.2.0.1', // override the router address, will be auto-detected if not set
        keepAlive: true // if true, refresh the mapping ten minutes before the ttl is reached, default true
    })


    
    // Map public port 1000 to private port 1000 with TCP
    await client.map({
        localPort: 1000,
        protocol: 'TCP'
    })

    // Get external IP
    const externalIp = await client.externalIp()
    
    console.log('External IP:', externalIp)
    
    // Unmap all mapped ports
    client.close()
}
main()

Here's the error:

Node.js v18.18.2

It appears the client is attempting to bind to a closed socket. https://stackoverflow.com/a/56016615/1483977

Could you submit a PR with a fix? PMP seems to be broken on my router after an update, it's enabled in config but the ports are closed so I can only use UPnP at the moment.
