this is slow and often overloaded, but it's kind of cool when it
works. this translation method deals much better with the kind of
slang you'd see in telegram posts than any other method.

some telegram channels do not allow embedding of messages, but do
allow a preview to be shown on twitter. this preview is just embedded
in the html, and can be scraped out if no message was found.
technically this preview also contains image links, but they are to
very low resolution, thumbnail-style images so i decided not to
include them here.

this is no longer the case since image links are now forwarded by tgsa

long as their embed page is någorlunda the same.

telegram occasionally changes the upstream urls at which images are
served, with old/new partially overlapping in time afaict.
with this commit, a new endpoint is added to tgsa at
/img/$user/$post_id/$img_idx
which serves a redirect to the actual image url that telegram had
returned within the last hour (i.e. as per the cache).
next step is to use these image urls in the bbcode itself.

this lays the groundwork for adding another handler and returning
handler results as `anyhow::Result<rouille::Response>`.
needed for the image redirect stuff.

factor out a function to access telegram posts from the cache,
fetching them anew if required.
a small behavioural change means that the program now takes a write
lock when fetching a post, to avoid simultaneously fetching the same
post many times (quite likely once it serves image redirects).

Telegram expires certain links in messages after some (unknown) amount
of time; this commit is the first step to working around that by
providing an image URL proxy.
In order to do that, we tick two important boxes here:
1. Store an extensible data structure in the cache.
2. Expire them periodically.

When quoting a post containing a tgsa quote, the entire quote was
previously erased. Doing it this way will leave the Telegram link in it.

The link shortening was in place because posts with image URLs that
were too long would not get recognised as valid image links.
astral has fixed this after my report:

I verified this with the example post that has a bunch of images and
such in it.
Thanks astral!
