Rink-web 3 (#165)
Kind of silly that I'm already on the third iteration of the website.
But the previous one was a bit over-engineered and hard to maintain. I
actually can't even get it to compile anymore, it errors out while
trying to build the wasm binary.

So it was either migrate from sapper (which is deprecated and broken) to
svelte-kit (the successor to sapper), or to simplify. I simplified.

The new tech jenga tower is:
- Soupault for building the website
  - AsciiDoctor for the pages
  - cmark-gfm for processing the markdown in the github releases
  - Several plugins and scripts copied from my personal website
- Vite for compiling the javascript
- wasm-pack for building the wasm binary

Rink's website will now be completely static, so operating it is easier.
The javascript and wasm is quarantined to the index page where a rink
repl is active, the other pages are plain html.

The currency fetching is now a totally separate piece of code from the
website. It makes it simpler and requires less code to be loaded during
the regular cron job.

The javascript is way simpler now. It only manipulates the part of the
page that need to be dynamic. It also uses the token format machinery
instead of directly converting rink's output AST to html.

Pros:
- Way lighter, faster page load times.
- Easier to maintain.
- Site contains more information now. An about page, the manual, and a
releases tab with DL links.
- No more URL spam that makes search engines think the site is a content
farm.
- Actually acts as a REPL now so you can run multiple queries, use
`ans`, up/down arrows to re-run previous queries.
- Proper sandboxing - queries that timeout cause the worker to be killed
and restarted.
- Now has a progress indicator on downloading the wasm blob, which is
good on slow connections.

Cons:
- Even more of a custom setup than before.
- It doesn't work offline anymore. At least not until I add a new
service worker, which will be a real pain to debug.
- The interactive parts (the rink REPL) require javascript to work now.
- A lot of the old URLs like `/query/abc` and `/units/meter` are broken.
I think this is fine though. I can add redirects in nginx that point
them to `/?q=abc` and `/?q=meter`.

rink - TOML configuration file format.
endif::[]
Description
-----------
Rink's configuration file uses the TOML format.
Duration types accept common suffixes like `ms`, `s`, `h`, `d`, `y`.
Size types accept suffixes like `MB`.
Color strings are a set of keywords separated by spaces. The following
keywords are understood:
*black*, *red*, *green*, *yellow*, *blue*, *purple*, *cyan*, *white*::
Sets the color to that ANSI color.
*dim*/*dimmed*::
Uses a dimmed variant of the color instead of the bright variant.
*bold*, *italic*, *underline*/*under*, *strikethrough*::
Formatting.
*hidden*/*none*::
Makes the text invisible.
*on*::
The color keyword after this will apply to the background instead of
the foreground. Example: `black on red`.
*default*/*plain*::
Results in unstyled text.
integers 0 to 255::
Extended terminal color palette codes.
*#* <__6 hex letters__>::
Hex codes can be used to specify truecolor.
Example: `#000000`
*rgb(* <__red__> *,* <__green__> *,* <__blue__> *)*::
RGB values can be used to specify truecolor. No spaces are allowed.
Example: `rgb(10,10,10)`
