Supports broader architectures in PE scanner

Browse Source 
Updates the PE scanner implementation to support both 32-bit and 64-bit architectures.
Leverages `std::variant` and a generic `ImageNtHeaders` to abstract architecture-specific details.
Simplifies the logic for retrieving section data, generalizing the process for improved maintainability.
