Use hostname instead of IP with -d flag

[agc93]

When connecting to a specific PS4 using the -d flag, it would be helpful to support using a hostname rather than only an IP address. Is this something you'd consider?

The -d flag is used here: https://github.com/dhleong/ps4-waker/blob/master/bin/cmd.js#L156

It looks like we do get some info about the device in addition to the IP address from which it broadcasted its response to our query, so it's probably possible to filter on that. In fact it may even be as simple as adding another "or" there with something like || device['host-name'] === argv.device. However this may not be the network hostname, but rather just the device's label. I'm not sure what all would be involved in resolving a network hostname, if that's what you're wanting.

I only have one device myself so I probably won't get to this anytime soon, but I would welcome a PR ;)

I unfortunately also only have the one, and I'm none too swift with the JS unfortunately :P

I was using the home-assistant component that leverages this tool and it requires a static IP because reasons I guess. I've modified that component as a workaround for now.

@agc93, how did you modify the component to use a hostname? Was your issue related to having ps4-waker and home-assistant in different subnets? This is the problem I'm trying to solve at the moment.

@jcconnell I've only got the one PS4 so I just removed the -d flag entirely from the _run method (around line 310) and put a fake value in to fool the config validation.

I have my PS4 and HA in the same subnet, just it's on DHCP so the IP would change.
