feat: added tests for createWindow and unpack, moved jest.setup.ts to…

… the root, installed jest-mock-extended (#51)

## Changes

* Added tests for `unpack` and `create-window`
* Added `jest-mock-extended` to improve type safety
* Added missing `archive.mjs` that was lost in one other PR and is
needed for the future build
