Getmac

192.168.16.254` with no errors or warning whatsoever.
* Significantly improved default interface detection. Default
interfaces are now properly detected on Linux and most other
POSIX platforms with `ip` or `route` commands available, or the
`netifaces` Python module.

Dev
* Makefile
* Vagrantfile to spin up testing VMs for various platforms using [Vagrant](https://www.vagrantup.com/docs/)
* Added more samples of command output on platforms (Ubuntu 18.04 LTS)

Changed
* Fixed macOS arp when MAC has one character sections in specific cases (Fixes issue 92)

Added
* Support BusyBox's ``arping``

Changed
* Improve how ARP is handled. If ``ArpFile`` method succeeds, use it instead of ``ArpingHost`` (this should fix [86](https://github.com/GhostofGoes/getmac/issues/86), for realsies this time).
* Speed up the first call to ``ArpingHost``
* Fix FORCE_METHOD not being respected for IPv4 macs

Changed
* Fix `ArpFile` method being used for IPv6 (`/proc/net/arp`, and ARP in general, is IPv4-only)

Changed
* Fix flakiness with UuidArpGetNode on MacOS by making it the last method attempted (Fixes issue [82](https://github.com/GhostofGoes/getmac/issues/82))

Changed
* Deprecate Python 3.6 support (support will be removed in getmac 1.0.0)

Dev
* Fix links in README and PyPI metadata to use "main" instead of "master" for primary branch
* Remove "Documentation" link from PyPI (the ReadTheDocs site is broken and hasn't been updated since 0.5.0)
* Add PyPI classifiers for 3.10 and 3.11
* Some cleanup of CHANGELOG
