useCapacitorFileStore

`useCapacitorStore` can be used as a boilerplate.
- [ ] in provider props handler as `handleFilePath: (key: string) => ({ path: string; directory: string; })`
- [ ] it should be possible to store all keys in one file, or each key in different file and directory based on `handleFilePath` (name can be changed)
- [ ] new store type should be added to the example
> open deepcase/deepcase in gitpod, `npm ci`, `npm run gulp -- packages:get` and then `cd packages/store-example` `PORT=3002 npm run dev`
> `useCapacitorStore` should work with both localStorage and capacitor store for first data sync. In case of `useCapacitorFileStore` this is impossible.
