[new release] opam-monorepo (0.2.2)
[new release] opam-monorepo (0.2.2)

CHANGES:

### Added

- Add `--ocaml-version` argument to `lock`: it allows to determine the ocaml version in the
  lockfile that's being generated (ocamllabs/opam-monorepo#161, @pitag-ha)

### Changed

- Exclude packages depending on `jbuilder` from the lock step. Since dune 2.0, `jbuild` files are
  not supported. A new `--allow-jbuilder` option have been added to enable the old behavior.
- Recognize packages with an optional dependency on dune as building with dune. This allows
  opam-monorepo to rightfully recognize `opam-file-format` latest versions as building with
  dune. (ocamllabs/opam-monorepo#176, @NathanReb)
- Only print the full list of selected root packages once and only in verbose mode, simply printing
  the number in the default logs. (ocamllabs/opam-monorepo#173, @NathanReb)
- Improve the solving process so it only accepts base-compilers unless one explicitly requires
  a compiler variant, either directly or using `ocaml-option-*` packages. (ocamllabs/opam-monorepo#178, @NathanReb)

### Deprecated

### Fixed

- Fix the default branch mechanism when the opam remote starts with `git+https` (ocamllabs/opam-monorepo#166, @TheLortex)
- Fix a log that was still refering to the old tool name `duniverse` (ocamllabs/opam-monorepo#158, @rizo)
- Improve how the default branch for a git repository is queried, fixing a bug
  where opam-monorepo wouldn't work outside of of git repo and a bug where it wouldn't
  work on non-english systems. (ocamllabs/opam-monorepo#157, fixes ocamllabs/opam-monorepo#114, @TheLortex)
