Subscribable Bug: state merge does not invoke sub-path subscription callbacks

[speigg]

const state = hookstate({
  a: 0,
  b: 0
}, subscribable())

state.a.subscribe(() => console.log('a changed'))

state.a.set(1) // logs `a changed`
state.merge({a: 42}) // does not log `a changed`

Ok I will get it fixed. It is possible to fix, it will not be a trivial one.

fix is coming in the next version. Have a look at the fix. I could not think of any better one.
