remove updater as a dependency (#41)

The upstream package was refactored and doesn't exist anymore.
The functionality is actually being implemented in #34 so the correct
dependencies will be added there.

Because the updater package is missing, the dependency manager is corrupting the
dependency cache for various pull requests.

Closes #39
