[Feature] Add Support for Getting MIME Type

[XmmShp]

Hi, great work on FileTypeChecker!

In many practical scenarios—such as serving files over HTTP, handling file uploads in web applications, or generating proper response headers—it's also essential to obtain the standard MIME type .

Could you please consider adding a feature to return the corresponding MIME type for detected file types? Just add a property string MimeType{get;} into IFileType

Thanks for considering this enhancement!

Thanks for the feedback and for engaging with FileTypeChecker – really appreciate it!

Since you find the project useful, please consider giving it a ⭐, contributing, or supporting the project to help keep it maintained and growing.

Your suggestion is interesting, though I want to carefully consider if and how it fits the library's philosophy.

Could you share a specific use case or code example where you'd use this feature? Understanding the exact scenario would help me evaluate whether this belongs in the core library or might be better as a separate mapping utility. I do not know if you know about FileTypeChecker Web Package

Thanks!

Will be included in version 4.3.0
