feat: improve Store API

[weboko]

This is a feature request

Problem

Store protocol seems to be overloaded with additional definitions such as cursor, page etc. For novice people it might be overwhelming.

Proposed Solutions

Make Store compatible with ISubscriber interface and hide difficulties behind good default. If someone would need to customize query - they would fall back to old API.
