* fix(lib): show error message detail when hitting some common flows
Instead of giving the user nothing to go off of, this patch gives them
an opaque blob of ROT-13 encoded base64. The logic is that if you are
smart enough to figure out how to decode this, you're probably smart
enough to either fix your broken client or give it to the adminstrator.

* fix(worker): constrain nonce value to be a whole integer
Closes#1043
Sometimes the worker could get into a strange state where it has a
decimal nonce, but the server assumes that the nonce can only be a whole
number. This patch constrains the nonce to be a whole number on the
worker end by detecting if the nonce is a decimal number and then
truncating away the decimal portion.

* fix(lib): ensure issued challenges don't get double-spent
Closes#1002
TL;DR: challenge IDs were not validated at time of token issuance. A
dedicated attacker could solve a challenge once and reuse it across
multiple sessons in order to mint additional tokens.
With the advent of store based challenge issuance in #749, this means
that these challenge IDs are only good for 30 minutes. Websites using
the most recent version of Anubis have limited exposure to this problem.
Websites using older versions of Anubis have a much more increased
exposure to this problem and are encouraged to keep this software
updated as often and as frequently as possible.

- Import @aws-crypto/sha256-js to use in Firefox as its implementation
of WebCrypto doesn't jump directly from highly optimized browser
internals to JIT-ed JavaScript like Chrome's seems to.
- Move the worker code to `web/js/worker/*` with each worker named after
the hashing method and hash method implementation it uses.
- Update bench.mjs to import algorithms the new way.
- Delete video.mjs, it was part of a legacy experiment that I never had
time to finish.
- Update LibreJS comment to add info about the use of
@aws-crypto/sha256-js.

* feat(lib): use new challenge creation flow
Previously Anubis constructed challenge strings from request metadata.
This was a good idea in spirit, but has turned out to be a very bad idea
in practice. This new flow reuses the Store facility to dynamically
create challenge values with completely random data.
This is a fairly big rewrite of how Anubis processes challenges. Right
now it defaults to using the in-memory storage backend, but on-disk
(boltdb) and valkey-based adaptors will come soon.
