Fix audit warning with CRA update

[jetXS]

Users might notice when installing the project or deploying (dependabot) that they are "security warnings".

Those security warnings can be safely ignored as they affect backend code which the project doesn't rely on. This backend code is used to build the project.

It is widely reported @ Create-React-App / Facebook folks and is awaiting the following pr to be merged facebook/create-react-app#12172

Similar issues were already reported by React users:
facebook/create-react-app#11801

This issue goes extensively into why it can be ignored:
facebook/create-react-app#11174

Fixed with @kyeshmz PR #16 and removal of CRA need. 8bfa446
