v0.9.5.0

• Rank N typing (see https://github.com/granule-project/granule/blob/dev-minor/examples/rankN.gr)

• Algebraic effects and handlers. See e.g.,

  • https://github.com/granule-project/granule/blob/dev-minor/examples/effects_nondet.gr
  • https://github.com/granule-project/granule/blob/dev-minor/examples/effects_state.gr

• Updated standard docs

• Fixes to deriving copyShape and drop combinators

• push deriving combinators now have Pushable constraint, e.g.

      pushList : forall {s : Semiring, r : s, a : Type}
                . {(1 : s) <= r, Pushable r} => (List a) [r] -> List (a [r])
      pushList = push @List
  

• Minor tweaks to the Granule Language Server to improve vscode interaction (no longer complains on the entire file about 'Premature end of file' whilst typing).
