mime types with charset parameter is not handled

[JochenDiekenbrock]

If the swagger document contains a mime type with a charset parameter, for example

      consumes:
        - application/json;charset=UTF-8

the generated api does set not a type definition,

type: ContentType.Json,

is missing.
