Hello I am loving PDF pig so far threw like 200 different pdf's at it no problem but now ran into 1 that is giving an error:

UglyToad.PdfPig.Core.PdfDocumentFormatException HResult=0x80131500 Message=Could not find the object 2 0 with type DictionaryToken. Source=UglyToad.PdfPig StackTrace: at UglyToad.PdfPig.Parser.Parts.DirectObjectFinder.Get[T](IToken token, IPdfTokenScanner scanner) at UglyToad.PdfPig.PdfFonts.Parser.EncodingReader.Read(DictionaryToken fontDictionary, FontDescriptor descriptor, Encoding fontEncoding) at UglyToad.PdfPig.PdfFonts.Parser.Handlers.Type1FontHandler.Generate(DictionaryToken dictionary) at UglyToad.PdfPig.PdfFonts.FontFactory.Get(DictionaryToken dictionary) at UglyToad.PdfPig.Content.ResourceStore.LoadFontDictionary(DictionaryToken fontDictionary) at UglyToad.PdfPig.Content.ResourceStore.LoadResourceDictionary(DictionaryToken resourceDictionary) at UglyToad.PdfPig.Parser.PageFactory.Create(Int32 number, DictionaryToken dictionary, PageTreeMembers pageTreeMembers, Boolean clipPaths) at UglyToad.PdfPig.Content.Pages.GetPage(Int32 pageNumber, Boolean clipPaths) at UglyToad.PdfPig.PdfDocument.GetPage(Int32 pageNumber) at UglyToad.PdfPig.PdfDocument.<GetPages>d__32.MoveNext() at System.Collections.Generic.List1..ctor(IEnumerable1 collection) at System.Linq.Enumerable.ToList[TSource](IEnumerable1 source) at pdftest.test.d33.MoveNext() in \pdftest\test.cs:line 251 at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() at pdftest.test.d31.MoveNext() in \pdftest\test.cs:line 209`

It is not the biggest issue for what I am using this for since the majority of pdf's work fine, but I figured it be useful for you guys to know this.

Hi @Smurfj3 thanks for the issue report, I think this is the same problem encountered in https://github.com/UglyToad/PdfPig/issues/208, if you're able to would you be able to try updating to the latest pre-release NuGet package https://www.nuget.org/packages/PdfPig/0.1.3-alpha001 which should fix this please? Let me know if it doesn't fix the problem and I'll take another look, thanks :)

So sorry for my late reply, I was just reporting it to be helpful, totally forgot about it because it only happened to me like once over like 1000 pdf's. Anyways, YES the latest pre-release fixes the issue! Thank you so much.
