Permanent exception in `Microsoft.FileFormats.PDB.PDBFile.ReadDirectory()`

Microsoft.SymbolStore v1.0.405901
Windows 10 Pro 22H2 x64 Build 19045

Exception on parsing Windows PDB file, because one of stream sizes is 0xFFFFFFFF:

ERROR: System.AggregateException: One or more errors occurred. (Arithmetic operation resulted in an overflow.)

There is no any checking for streamSizes[i] here:

symstore/src/Microsoft.FileFormats/PDB/PDBFile.cs

Lines 60 to 61 in 65e1cd4

 streams[i] = new Reader(CreatePagedAddressSpace(directoryContent, position, streamSizes[i])); 
 position += ToPageCount(streamSizes[i]) * sizeof(uint); 

P.S. v1.0.215101 has no errors!!!

This has been fixed in PR #401.
