Cping

* Added Python 3.10 to CI.
* Code restructuring and cleanup.

> Upgrade with `pip3 install -U cping`

* cPing closes a bit faster (it used to wait for any remaining pings to complete).
* Minor code cleanup.

> Upgrade with `pip3 install -U cping`

* Added an indicator to the column by which the table is being sorted.
* Improved responsiveness when stopping a host or toggling burst mode.

> Upgrade with `pip3 install -U cping`

* Introduced a new, interactive layout that allows you to sort the output, use burst mode ping, start/stop one or more hosts. It also has a sparkline to visualize latency.
* Using sockets for ICMP as opposed to screen-scraping, making `cPing` more efficient. Still does **not** require root.
* Internals rewrote; it's easier to extend `cPing`, like a new layout or protocol.
* Windows support.

This is a re-release of v0.1.1 which (also) had an installation bug using PyPI.
