Feat/to model operator

[aalamu]

Description:

This PR introduces a new toModel operator that transforms an observable stream by mapping emitted values to instances of a specified model class.

The operator simplifies the process of converting raw data (e.g., from API responses) into model instances, improving type safety and reducing boilerplate code.

It follows the existing RxJS operator patterns and is fully tested.

Usage:

apiService.getData()
  .pipe(toModel(Person))
  .subscribe(userInstance => {
    // userInstance is now a Person object
  });

@aalamu, thank you for the effort, however, RxJS core is trying to reduce core API surface and it doesn't accept new operators for now. Please create your operator in user-land space (by creating your own open source repository or NPM package).

The operator suggested in this PR is very simple and can be created with using map operator, so it most probably won't be included in library as such. This is how to use it with map operator:

.pipe(map((arg) => new Person(arg)))
