Thanks, codespell!

The Debian packages benefit from security support and should be much
easier to install for most users.

Currently all requirements of Auro Engine are packaged in Debian.
Thus the virtualenv-related documentation snippets can be removed.

In addition to porting it to python3, a number of documentation and code
issues were solved:

* doc: proper order of arguments
* doc: mention debug mode (previously via "__debug__", now "DEBUG=1")
* doc: provide example for manual heartbeat packets
* code: specify timeout for "socket.recvfrom" (avoid hanging)
* code: handle parameters properly (cast to int/float)
* style: format with "black"
