Proper type safety

[zzarcon]

• update method return any:
  

  xtore/src/xtore.ts

  Line 34 in ff8e952

  update(id: string, state: any) {

• private store any 😢

  xtore/src/xtore.ts

  Line 10 in ff8e952

  private store: {[id: string]: any};

Proposal 1

xtore.update('user', '123', {name: 'hector'});

xtore.subscribe('user', '123', {
  next() {

  }
});
