fixes NullToken for a font ( #284 )
...
font was in a streamObject, PdfTokenScanner.ParseObjectStream would return a NullToken
DirectObjectFinder.Get would then throw on line 79, even thus it should handle null tokens (i.e. ResourceStore.LoadFontDictionary line 152)

Fix buggy font ( #283 )
...
* Adds checksum on font file reading
* fix name table parsing on broken table
* only warn if checksum invalid, avoid exception with bounds check #258
also returns a null object when the object generation number exceeds
ushort.maxvalue since this is the maximum allowed value and this
broke tests attempting to parse all objects in the file from #258
* remove potentially problematic document
it might be sensitive data
* use ttf from file to test without including full file
