RFC: simple state machilne-like helper

[AlexandrHoroshih]

https://share.effector.dev/q6bVhnK5 - live example

Creates a store with predefined set of possible states and defines possible transitions between them

const lightMatrix = {
  green: 'yellow',
  yellow: 'red',
  red: 'green'
};

const [$light, next] = createMatrix(lightMatrix, 'green');

next() // $light: yellow
next() // red
next() // green

Requesting another API:

const next = createEvent();

const $light = createMatrix({
  matrix: lightMatrix,
  initial: 'green',
  clock: next,
});

Cool, that's better and more effector-style api
