 ### Whats' new in v4?
-  - Complete Rewrite, latest dependencies with minimal API changes.
-  - Redundant `parseStrict()` and `validate()` functions are removed.
-  - Strict mode is configurable via options. 
-  - Console errors if parser functions for block is not avaiable. Strict Mode throws errors.
-  - Code is more readable, modular. It would make it easier to contribute and track changes. 
-  - Type definitions directly fetched from Editor.js, so development becomes easier.
-  - Unit Testing with Jest.
