* Refactor anubis to split business logic into a lib, and cmd to just be direct usage.
* Post-rebase fixes.
* Update changelog, remove unnecessary one.
* lib: refactor this
This is mostly based on my personal preferences for how Go code should
be laid out. I'm not sold on the package name "lib" (I'd call it anubis
but that would stutter), but people are probably gonna import it as
libanubis so it's likely fine.
Packages have been "flattened" to centralize implementation with area of
concern. This goes against the Java-esque style that many people like,
but I think this helps make things simple.
Most notably: the dnsbl client (which is a hack) is an internal package
until it's made more generic. Then it can be made external.
I also fixed the logic such that `go generate` works and rebased on
main.

Closes #65
Pull request images will now be `ttl.sh/techaro/pr-{number}/anubis:24h`.

The example/default bot policy document had a rule to allow RSS readers
through based on paths that end with ".rss", ".xml", ".atom", or
".json". Frameworks like Rails will treat these specially, meaning that
going to /things/12345-whateverhaha.json could bypass Anubis.
I checked the history of this rule and it was present in the original
example policy file in Xe/x. This rule is likely a mistake and it has
been removed. I think it was for making my blog still work with RSS
readers.
Thanks to Graham Sutherland for reporting this over email.

Closes #30
Introduces the "challenge" field in bot rule definitions:
```json
{
"name": "generic-bot-catchall",
"user_agent_regex": "(?i:bot|crawler)",
"action": "CHALLENGE",
"challenge": {
"difficulty": 16,
"report_as": 4,
"algorithm": "slow"
}
}
```
This makes Anubis return a challenge page for every user agent with
"bot" or "crawler" in it (case-insensitively) with difficulty 16 using
the old "slow" algorithm but reporting in the client as difficulty 4.
This is useful when you want to make certain clients in particular
suffer.
Additional validation and testing logic has been added to make sure
that users do not define "impossible" challenge settings.
If no algorithm is specified, Anubis defaults to the "fast" algorithm.

* cmd/anubis: drastically optimize proof of work
Closes #12
Closes #17
This drastically optimizes the proof of work check by removing the
stringify call at every iteration. Additionally, this optimizes the
checks by running them in parallel for as many threads as the browser
has available (according to navigator.hardwareConcurrency).
This also changes the redirect lag to 250 milliseconds instead of 2000
milliseconds in order to be perceptually faster. This is below the
reaction time threshold of many people, so this will make the post-check
success phase perceptually instant.
Testing on an iPhone 7 Plus has shown that this can clear a difficulty 4
check in 3.4 seconds.
This actually optimizes the check so much it may be a logistical concern
for operators.
