NixHTTPPathInfoService acts as a bridge in between the Nix HTTP Binary
cache protocol provided by Nix binary caches such as cache.nixos.org,
and the Tvix Store Model.
It implements the [PathInfoService] trait in an interesting way: Every
[PathInfoService::get] fetches the .narinfo and referred NAR file,
inserting components into a [BlobService] and [DirectoryService], then
returning a [PathInfo] struct with the root.
Due to this being quite a costly operation, clients are expected to
layer this service with store composition, so they're only ingested
once.
The client is expected to be (indirectly) using the same [BlobService]
and [DirectoryService], so able to fetch referred Directories and Blobs.
[PathInfoService::put] and [PathInfoService::nar] are not implemented
and return an error if called.
This behaves very similar to the nar-bridge-pathinfo code in nar-bridge,
except it's now in Rust.

Allow taking advantage of the buffer of the underlying reader to avoid
unnecessary copies of file data.
We can't easily implement the methods of BufRead directly, since we
have some extra I/O to perform in the final consume() invocation.
That could be resolved at the cost of additional bookkeeping, but this
will suffice for now.

This allows converting from the NarInfo falling out of the NarInfo
parser (which is a bit annoying to handle due to lifetimes) to the
PathInfo proto struct.
The narinfo field, containing most of the data from the original
NARInfo file, as well as the references (bytes) are populated.
The node field is not populated, because it requires ingesting the NAR
itself to describe the root node.

This was due to the user-agent field. The regex is now fixed.

not via IAM,
In any case, there's no point failing to parse if a single line doesn't
match the regex - we can just skip them.
For the sake of completeness, logs for that day have been reprocessed

`keymap.c`), and then build that as a makefile target.
`via` is *disabled*, as their keybindings take priority over keymap.c.
Luckily, only `qmk` seems to be sufficient to build it.
A simple `:flash` target/script is provided as well, it relies on some
udev rules set in the global system
(`hardware.keyboard.qmk.enable = true`).

````
… and will produce a zstd-compressed Parquet file for (roughly) that
time range.
As the EC2 instance credentials don't give access to the logs bucket
(yet), other AWS credentials need to be provided.
This can be accomplished by using "AWS_ACCESS_KEY_ID",
"AWS_SECRET_ACCESS_KEY", "AWS_SESSION_TOKEN" from
"Option 2: Manually add a profile to your AWS credentials file (Short-
term credentials)" in AWS IAM Identity Center.
Processing logs for a one-hour range takes a minute or two, the
resulting zstd-compressed Parquet file is around 40-80M in size.
Processing logs for a whole day takes some 25mins, due to the sheer
amount of data (12 GB of raw log data, distributed among 450k individual
files, 20Mio log lines), but at least clickhouse isn't able to parse the
resulting parquet file back in:
