Log Message:
ocaml-digestif: update to 1.1.0.

### v1.1.0 2021-10-11 Paris (France)

- Add Keccak256 module (ethereum padding) (@maxtori, @dinosaure, #118)
- Update README.md to include the documentation (@mimoo, @dinosaure, 65a5c12)
- Remove deprecated function from `fmt` library (@dinosaure, #121)
- **NOTE**: This version lost the support of OCaml 4.03 and OCaml 4.04.

### v1.0.1 2020-02-08 Paris (France)

- Fix `esy` support (@dinosaure, #115)
- Fix big-endian support (@dinosaure, #113)

### v1.0.0 2020-11-02 Paris (France)

- **breaking changes** Upgrade the library with MirageOS 3.9 (new layout of \ 
artifacts)
  Add tests about compilation of unikernels (execution and link)
  (#105, @dinosaure, @hannesm)
- Fix `esy` installation (#104, @dinosaure)
- **breaking changes** Better GADT (#103, @dinosaure)
  As far as I can tell, nobody really use this part of `digestif`.
  The idea is to provide a GADT which contains the type of the hash.
  From third-part libraries point-of-view, it's better to _pattern-match_ with
  such information instead to use a polymorphic variant (as before).
- **breaking changes** key used for HMAC is a constant `string` (#101, \ 
@dinosaure, @hannesm)
  The key should not follow the same type as the digest value (`string`, \ 
`bytes`, `bigstring`).
  This update restricts the user to user only constant key (as a `string`).
