Angular v21 is now supported.

v2.0.0

Remove unneeded code and injector requirement.

Move BroadcastChannel initialization into afterNextRender().

### v2.0.0 (Pre-release)

#### Breaking changes:
* TypeScript version 5.6+ is required.

This library still works with Angular v16+, but if you use the strict peer dependencies setting (enabled by default) in your package manager, TypeScript version 5.6+ is only supported by Angular v19.

This is caused by a different method of importing the localForge library, and this method is required for SSR support.

#### New features:
* SSR is now supported 🎉

You no longer need to wrap storage initialization in `afterNextRender()`. If you require SSR support, you can do so by providing an `Injector` instance in the constructor. If SSR support is not needed in your app, no changes are required.

Angular v18 is now supported.

…age anymore.

Fix: Do not emit an observable and signal if no value is found during…

… the initial read in the storage.
