515076b741 Organizes PE scanner code into namespaces
Refactors the PE scanner implementation to group related definitions and functions within namespaces.

This improves code organization and readability, particularly for internal PE handling and scanning logic.

0d01309bf8 Refactors PE scanner to eliminate redundant section extraction
Simplifies the PE pattern scanner by removing the redundant `extract_section_from_pe_file` function.

The extracted data is now returned directly from a new `ExtractedSection` struct within the main scanning function, streamlining the code and reducing duplication. This improves readability and maintainability of the PE scanner.

656b1a2267 Allows specifying target section for file scan
Enables users to specify the target section name when scanning a PE file for a pattern.
This provides more flexibility in locating patterns within a PE file, as it's not limited to the ".text" section.

84b9500837 Removes platform-specific error handling
Simplifies pattern scanner logic by removing conditional compilation for non-Windows platforms.

The error handling previously thrown on non-Windows platforms was unnecessary as this functionality is not intended for those systems. This change streamlines the code and removes a misleading error message.

f1ee6e9e35 Supports broader architectures in PE scanner
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.

5ea1f00d09 Adds PE scanner infrastructure and data structures
Initializes infrastructure for PE file scanning.

Adds data structures for PE headers (DOS, optional, section),
including user-defined types for section characteristics.

Refactors existing pattern scanning code to utilize new PE data structures.

Adds basic parsing of PE headers.

007340edaa Adds PE file header definitions
Defines `DosHeader` and `FileHeader` structures to represent PE file header information.
Includes definitions for `MachineId` enum and `FileCharacteristics` union.
These definitions are prerequisite for PE file parsing and analysis.

b9c5dcc2c5 Adds PE section extraction and pattern scanning
Adds functionality to extract a specific section from a PE file and scan for a given pattern within that section.

Introduces `extract_section_from_pe_file` to isolate a section, enabling more targeted pattern searches.
Overhauls `scan_for_pattern_in_file` to utilize extracted section data and improve accuracy.
