CI Release Flow (AxisCommunications#89)

* CI Release Flow

How it works:

1. Everytime a PR is merged, the changeset
   action creates (or updates) a PR with
   the generated changelogs for review.

2. When we are ready for a new release,
   we merge the changelog PR.

3. A new release is automatically built
   and uploaded to npm.

4. A GitHub release entry is automatically
   created.

Note: The generated changelogs are now
excluded from prettier, because forcing it
made the release process awkward. It does
not really matter that much, since the
changeset action seems to follow prettier's
standards close to 100%.
