Steam.Models.PublishedFileDetailsModel FileSize should be of type ulong

[sezonis]

Some workshop items are bigger than the max value of unit32, therefore it proceeds with this response

Error converting value "22491603309" to type 'System.UInt32'. Path 'response.publishedfiledetails[0].file_size', line 1, position 225. ---> System.OverflowException: Value was either too large or too small for a UInt32

Solution is pretty basic.
