Update MimeTypes database (eg. *.msg is missing)

[BeJoNe]

I was thankfully using your wonderful library but got stuck on getting the mimetype for an outlook "message.msg" file..

So, for the mapping-part of "file-extensions to mimetypes" I added
https://www.nuget.org/packages/MimeMapping
to my project:

The Dictionary is generated from the https://github.com/jshttp/mime-db#mime-db
Works similar to .NET's https://learn.microsoft.com/dotnet/api/system.web.mimemapping.getmimemapping).

It aggregates data from the following sources:
https://www.iana.org/assignments/media-types/media-types.xhtml
https://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
https://hg.nginx.org/nginx/raw-file/default/conf/mime.types
The library is just a literal C# Dictionary<string, string> with over 1000 entries, and a helper method that can be passed a file path.

Is there a chance using this class in your library (and save your time) ?
