The differences between IPv4 and IPv6 APIs can be moved to a single type so that we don't need to keep track of them all over the code. We can also split Run() into two parts: the top one sets up the listener and the bottom one sends and receives packets. In this way, the bottom part can be tested using a mock packet connection.
* Fix unprivileged packet matching on Linux
* Compute statistics on-the-fly as packets are received

Move the DNS resolver out of the NewPinger() function in order to allow
adjusting of IPv4 vs IPv6 DNS resolution before running. This also
allows the user to verify resolution.
* Create new `New()` method that returns a bare default struct.
* Create new `Resolve()` method.
* Call `Resolve()` from `SetAddr()`.
* Call `Resolve()` automatically from `Run()`.
* Remove unecessary private `run()` method.
Update ping command for simplifed return values of `NewPinger()`.
