Use template-literal instead of EJS

[Template Literal](https://github.com/Drulac/template-literal) is fastest, smallest and simplest template engine, because it use JS's literal template feature,

It's 55 times faster than EJS, so it may be a good idea to use it instead of EJS 😀

Start by locating where EJS is currently used and how template output is tested. Compare the existing behavior with the proposed template-literal engine, then confirm that replacing EJS preserves the project's tests and supported functionality.
