feat!: Add hooks to store

* For easier access and to avoid context issues with injections hooks are put into the store
* hooks can be accessed and will emit events when the flow has bound its emit function to the hooks
* useHooks and useStore are not exported anymore! Instead, useVueFlow is provided, which will return an instance of the current vue flow store
* Rename NodeIdContextKey to NodeId
* Add addElements function to store to add elements without having to re-set the whole store
* use v-model for elements, re-set elements only if there's an actual change
