Regenerate protos and update protobuf constraint (dart-archive/appeng…

…ine#182)

* Allow newer protobuf versions

* Regenerate protos and update protobuf constraint

Improves/changes the regeneration script:
* Use the protoc_plugin from the pubspec.yaml - so the constraint is
  fixed
* Move it to `tool/` for better discovery.
* Mention in `README.md` for better discovery.
* Clone into `tmp/` so we don't have to redownload everything
* Compile all protos in one command (much faster)
* Use `dart format` instead of `dartfmt` (actually works on modern SDK).

Prepares for a new publication.

* Remove obsolete test script

* Fix tests
