Move to maintained `if-addrs` crate #69

	# Based on https://github.com/actions-rs/meta/blob/master/recipes/quickstart.md
	#
	# While our "example" application has the platform-specific code,
	# for simplicity we are compiling and testing everything on the Ubuntu environment only.
	# For multi-OS testing see the `cross.yml` workflow.
