[new release] digestif (1.0.0)

CHANGES:

- **breaking changes** Upgrade the library with MirageOS 3.9 (new layout of artifacts)
  Add tests about compilation of unikernels (execution and link)
  (mirage/digestif#105, @dinosaure, @hannesm)
- Fix `esy` installation (mirage/digestif#104, @dinosaure)
- **breaking changes** Better GADT (mirage/digestif#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` (mirage/digestif#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`).
