Dry install 🏜️

Dry install with the current Coq version:

Command
opam install -y --show-action coq-huffman.8.16.0 coq.8.5.0~camlp4
Return code
5120
Output
[NOTE] Package coq is already installed (current version is 8.5.0~camlp4).
The following dependencies couldn't be met:
  - coq-huffman -> coq >= 8.12 -> ocaml >= 4.05.0
      base of this switch (use `--unlock-base' to force)
  - coq-huffman -> coq >= 8.12 -> coq-core -> ocaml >= 4.09.0
      base of this switch (use `--unlock-base' to force)
No solution found, exiting

Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:

Command
opam remove -y coq; opam install -y --show-action --unlock-base coq-huffman.8.16.0
