refactor(module division): modules divisions

BREAKING CHANGE: extensions (On, method) are in a separate modules,
mockFactory changed interface, name (Provider) and module

Importing On, method changed:

Before:
import { On, method } from "ts-auto-mock";

After:
import { On, method } from "ts-auto-mock/extension";

MockFactory changed name, module and interface:

Before:
import { MockFactory } from "ts-auto-mock";

MockFactory.instance.registerFactory((name: string, value: any) => {
    ...
});

After:
import { Provider } from "ts-auto-mock/extension";

Provider.instance.provideMethod((name: string, value: any) => {
    ...
});
