Return Store and StoreWritable<T> whenever it is meaningful

[agadoev]

Now in the documentation and reshape function signature return value is Store, but in fact it is ReadonlyStore. It can be reproduced by decomposing some stores with reshape and trying to modify it with .on(). An error message will appear in the browser console.

I suggest explicitly defining ReadonlyStore type as the return value of reshape function.

[agadoev]

now this code

const { $part1, $part2 } = reshape({
  source: $complexData,
  shape: {
    $part1: (complexData) => complexData.part1,
    $part2: (complexData) => complexData.part2
  }
})

is the same as this code

const $part1 = $complexData.map(complexData => complexData.part1)
const $part2 = $complexData.map(complexData => complexData.part2)

I think it would be really useful if reshape returned a simple store, changing which would cause the parent store changes.

@agadoev At the moment effector has no defined ReadonlyStore.

https://github.com/effector/effector/blob/master/packages/effector/index.d.ts

It will be possible only after this change.
Keep track of effector/effector#755

Store renamed into StoreWritable, but ReadonlyStore renamed into Store
