feature: add --prefer-types-over-interfaces options

[TiagoCerqueira]

Hello,

We have implemented this feature, with two reasons :

• We prefer use types over interfaces for our domain
• In our project we have a french named domain named "Document" and the name clash with the "Document" from MDN. https://developer.mozilla.org/en-US/docs/Web/API/Document
