Add bindings for ISteamRemoteStorage/GetCollectionDetails endpoint.
Added the GetCollectionDetails method to ISteamRemoteStorage which accepts either a single ulong or IList<ulong> via an overload and will return the list of items in that collection.
The uint FileType field on CollectionDetailItem appears to be some sort of enumeration, however I have only seen 0 returned for mods and 2 for collections, so I am hesitant to give it a concrete implementation.
@oliver4888 are you able to take a second look at this PR based on my comments so I can merge? Thanks.
Hey @babelshift, I don't see any comments.
Also I believe the FileType corresponds to EWorkshopFileType however the partner docs don't appear to have GetCollectionDetails so I'm not 100% on this.
