devel/hs-primitive-unlifted: Update to 2.1.0.0

2.1.0.0 -- 2023-06-28
* Change the order of the type arguments to UnliftedArray_ and
  MutableUnliftedArray_. This makes the library work better with the
  typeclasses in the contiguous library.

2.0.0.0 -- 2023-06-27
* Use legitimate unlifted primitive types and operations, only supporting
  GHC 9.4 and newer.

1.0.0.0 -- 2020-11-02
* Redo everything. This uses unsafeCoerce# a lot to coerce between lifted
  and unlifted types. Stay on the 0.1.x.x series unless you need something
  from this newer version.
