djbdns-logparse: convert tinydns and dnscache logs to human-readable form

== What is it? ==

djbdns is Daniel J. Bernstein's suite of DNS software from,

  https://cr.yp.to/djbdns.html

Two of its daemons, tinydns and dnscache, resolve DNS queries while
simultaneously logging obscure gibberish to a file. For example, this
is what tinydns logs if I request the 'A' record for www.example.com:

  @4000000063227a320c4f3114 7f000001:9d61:be69 - 0001 www.example.com

djbdns-logparse converts these into something that you can actually
read. The line above gets turned into,

  2022-09-14 21:04:40.206516500 dropped query (no authority) from
  127.0.0.1:40289 (id 48745): a www.example.com

and surely you agree that this is preferable.


== Requirements ==

There are only two:

  a) python-3.6 or later, for f-strings support
  b) the tai64nlocal program from djbdns in your PATH


== History ==

This is a modernish fork of Greg Ward's parse_djbdns_log program
from,

  https://www.gerg.ca/hacks/parse_djbdns_log

The original was inspired by Faried Nawaz's dnscache log parser,
