refactor(pep-lib): replace DotNetZip with System.IO.Compression and refactor readers

Browse Source 
- Remove DotNetZip package from PepLib.Core.csproj
- Update DrawingReader, NestReader, and ZipHelper to use System.IO.Compression.ZipArchive
- Simplify stream handling and improve resource disposal
- Keep behavior consistent for loop/plate detection and extraction
