Adds an nmap and service detection features

[JustinTimperio]

At this point, this is a fairly experimental feature. Currently, I have been unable to get this to compile on windows so I needed to rework the file structure a little to make the feature os specific. I still need to submit an issue to the upstream package about windows support but it may just be an issue on my end. Overall I think this is still worth adding because of how powerful the feature actually is.

Here is what the output looks like (censored):

@JustinTimperio You know that the client PC needs to have nmap installed for your PR to work? Your dependency just instructs the real nmap program, therefore this PR doesn't work.

[JustinTimperio]

@lu4p I honestly hadn't tested this yet. For me, this was a proof of concept to see if it was possible to get this working. Your right, this is mostly useless if it can't be embedded.
