Fix the documentation of Digestif.S.hmac_feed_bytes

Upgrade setup-ocaml

Remove setup-dkml from CI

Prepare v1.3.0

Implement feedable hmac

Use CAMLextern in caml_ forward declarations

add x-maintenance-intent field to the opam file

Analogous to `ctx` and `feed_*` but for computing hmacs incrementally.
For when `hmaci_*` is not suitable.

Prepare v1.2.0

Implement get_into_bytes

Add lower bound on fmt

Add a new type hash', a polymorphic variant

We use `Fmt.str` etc. which is introduced in fmt.0.8.7.

The hash' type permits to manipulate hash implementations without the type information.
It can be useful when the user does not want to prove the type of the hash.

Oops.

get_into_bytes finalizes the hash and writes it to the buffer.

Update description to include SHA3

(It is not an acronym and usually written using lowercase)

Prepare v1.1.4

Fix primitives used for bytes

Add a test about CVE-2022-37454

Prepare v1.1.3

Delete the old MirageOS 3 trick

Such trick is to compile digestif with ocaml-solo5 and distribute
it for MirageOS 3 then. We need to patch the generated META file
from `dune` to finally install something good for MirageOS 3.

It seems clear that at this date, we don't really need to continue
the support of MirageOS. It seems that such trick bothers dune
cache and installation on some platform. Let's just remove that.

Use extern instead of caml/threads.h

test_conv.ml requires /dev/urandom and work only on Unix system

Support MSVC compiler

Prepare v1.1.2

raise to OCaml 4.07.0, remove dependency to compat packages
