Today the [ImageStack](https://github.com/silx-kit/silx/blob/main/src/silx/gui/plot/ImageStack.py#L148) is keeping all the loaded image in memory. But those images can be pretty large. It would be nice to have an option (or open the API) to have a [LRUCache](https://github.com/silx-kit/silx/blob/main/src/silx/gui/plot/items/_cache.py#L7) like.
