Replace the per-GroupListItem state indicating whether the item's submenu is
open with a per-GroupList state variable indicating which group (or none) has
its submenu currently expanded.

This transition is not as simple as applying a CSS transition
property to an element since browsers do not support animating `width`
/ `height` from 0px to "auto" to fit the content. Therefore add a
component to handle the steps in the transition.

Move load annotations to service

- Load annotations using the new annotations service.
- Use the new store isFetchingAnnotations rather than the previous
isLoading method to determine whether an annotation fetch is currently
in progress.

Instead of going through a layer of indirection (aka the groups
service) to get the focusedGroupId use the store directly.

This service issues an api request(s) to fetch all annotations
associated with all URIs and the group on the page. It also
loads all the annotations into the store, updates the frame
status upon completion, and updates the activeAnnotationFetches
count in the store.

fixup

Most of the configuration was moved into an updated version of the base
eslint-config-hypothesis package.

See https://github.com/hypothesis/frontend-toolkit/pull/6
