Since there isn't a very reliable way (in my opinion) to get the mime type of a specific extension, regardless of the file actually being of that type or not.
This type of thing usually is used when sending a different Content-type when you intend to send, for example, an image.

The functioning of the class is complete, but I'm aware that there are lots of missing mime types like the image/* or application/*.
What can I do to improve my code in quality and make a better class and (maybe) make it production-ready?
What should I improve in types of performance?
