Add initial EasyList class

[damskii9992]

Here is my initial thoughts on how the generic EasyList could look like. I haven't added tests yet, but please have a look.

• I understand that the lack of graph integration is a feature? We let the list components do the edge/vertex tracking?

• Good type safety but not sure we should allow duplicates. My ModelCollection just skips duplicates which might be even worse.

• Where is the data property? Do we need it?

• Where is the aggregate get_all_variables? Just run over all children and return that aggregate.

I think this will throw TypeError in min(stop...) if stop is left as ... (ellipsis can't be compared to int)

You might need to change it to stop: int | None = None instead

I can find no problems with the code, but it's also using some methods that are new to me, so I'm not an expert.

As discussed elsewhere, I'll want this exact class, but using something like name instead of unique_name.

From what I understand, we could make that somewhat straightforward by introducing something like

def _get_key(self, item: ProtectedType_) -> str:
    return item.unique_name

and replace calls to item.unique_name with self._get_key(item).
That way I can inherit from this class and override _get_key (and write my own validation to ensure the name is unique within the specific list).

This seems to me to be cleaner than maintaining a copy of EasyList in EasyDynamics.

I approve the name BTW.
