Role inheritance does not work

[miladabc]

Bug Report

Extending roles does not work as expected.
Code sample is taken from documentation.

script.js:

const roleAcl = require("role-acl");
const ac = new roleAcl();

ac.grant('user')
    .execute('read').on('video')
  .grant('admin')
    .extend('user')
    .execute('create').on('video')
    .execute('update').on('video')
    .execute('delete').on('video');

/path/to/script.js:8
  .execute('create')
   ^

TypeError: ac.grant(...).execute(...).on(...).grant(...).extend(...).execute is not a function
    at Object.<anonymous> (/path/to/script.js:8:6)

Environment

• node version: 12.15.0
• role-acl version: 4.3.2
• os: Ubuntu 18.04

Try this:

ac.grant('user')
    .execute('read').on('video')
  .grant('admin')
    .extendSync('user')
    .execute('create').on('video')
    .execute('update').on('video')
    .execute('delete').on('video');

or

(await ac.grant('user')
    .execute('read').on('video')
  .grant('admin')
    .extend('user'))
    .execute('create').on('video')
    .execute('update').on('video')
    .execute('delete').on('video');

extend is promise function so you need to user await before chaining with another execute on that, otherwise, you can use extendSync which is a sync function.
