Subscribe to nested structures

[vaaralav]

Instead of flat object give possibility to subscribe to observables in a nested object. Something like this:

/* isFetching, userList and selectedUser are ko.observables */
<KoSubscribe
        subscribe={{
          users: {
            isFetching,
            userList
          },
          selectedUser,
        }}
        render={({ users, selectedUser }) => (
          <div>
            <Profile user={selectedUser} />
            <Users {...users} />
          </div>
        )}
/>
