This doesn't return the digest, but the internal NixHash.
To get the digest, you use `ca_hash.hash().digest_as_bytes()`
(as done in tvix/nix-compat/src/derivation/write.rs).

The public-consumable thing here is ChunkedReader, not ChunkedBlob.
ChunkedBlob is a helper that can be used to get a new AsyncRead, but
not AsyncSeek. It is used internally by ChunkedReader whenever the
client seeks.
Make this more obvious, by extending the documentation, and putting
ChunkedReader at the top of this file.
Also make ChunkedBlob and its methods private, and give ChunkedReader a
more useful constructor (from_chunks, instead of from_chunked_blob).

mkBuild* is independent of the target abstraction, we can just use

When changing the buildkite pipeline code I found that some functions
have a lot of arguments where the order is not necessarily clear. To
ease further refactors / new features, I've ported them over to taking
attribute sets.
Note that this technically is a breaking change, as these functions are
all exposed. Not sure how often they'd be called from the outside,
though.

The primary addition is the `builtin_hashFile` function which attempts
value-path coercion and on success reads the file to a nix_string.
Similar to the `builtins_hashString` implementation, the hash is then
derived using the `hash_nix_string` function in the introduced hash
module which has extracted hashing functionality initially specified in
cl/11005.

This is done because the existing dependency from multi-user.target to

an actual dependency on the service.

nixery.dev uses the vnd.docker.container.image.v1 format, which is
recognized by the OCI [1] and originally defined by Docker [2]. The
config field in this image format, which this commit is about, is
even portable between the Docker and OCI formats (the Docker Golang
library embeds the OCI definition [3]).
The attribute names in what's called ImageConfig in [3] are specified as
PascalCase, which effectively means that the names Env and Cmd used by
nixery need to be capitalized. The lowercase variant is not causing a
lot of issues because most container tooling is written in Golang, which
allows case-insensitive matches when deserializing JSON. Languages that
parse strictly either miss the configuration values, or fail due to
unknown attributes. This commit capitalizes Cmd and Env to accomodate
strict parsers.

Previously, Nix strings were represented as a Box (within Value)
pointing to a tuple of an optional context, and another Box pointing to
the actual string allocation itself. This is pretty inefficient, both in
terms of memory usage (we use 48 whole bytes for a None context!) and in
terms of the extra indirection required to get at the actual data. It
was necessary, however, because with native Rust DSTs if we had
something like `struct NixString(Option<NixContext>, BStr)` we could
only pass around *fat* pointers to that value (with the length in the
pointer) and that'd make Value need to be bigger (which is a waste of
both memory and cache space, since that memory would be unused for all
other Values).
Instead, this commit implements *manual* allocation of a packed string
representation, with the length *in the allocation* as a field past the
context. This requires a big old pile of unsafe Rust, but the payoff is
clear:
hello outpath time: [882.18 ms 897.16 ms 911.23 ms]
change: [-15.143% -13.819% -12.500%] (p = 0.00 < 0.05)
Performance has improved.
Fortunately this change can be localized entirely within
value/string.rs, since we were abstracting things out nicely.
