Refactor JSON Parsing to Use Boost.JSON

[CharityKathure]

• supersedes / closes Refactor JSON Parsing to Use Boost.JSON #197

This pull request introduces significant changes to the LogMonitor project, primarily focusing on replacing the ConfigFileParser and JsonFileParser with a new JsonProcessor module. This includes the addition of new functions for handling different log types and updating the project files accordingly.

New JsonProcessor module:

• Added JsonProcessor.cpp with functions to load, parse, and process JSON configuration files, handling different log types such as EventLog, File, ETW, and Process logs.
• Added JsonProcessor.h with declarations for the new functions in JsonProcessor.cpp.

Project file updates:

• Updated LogMonitor.vcxproj to include JsonProcessor.cpp and JsonProcessor.h, and removed references to ConfigFileParser.cpp and JsonFileParser.cpp. [1] [2]
• Updated LogMonitorTests.vcxproj to include JsonProcessorTests.cpp and removed references to ConfigFileParserTests.cpp. [1] [2]

Test updates:

• Added a new test class JsonProcessorTests in JsonProcessorTests.cpp to test the new JsonProcessor functionalities.
• Updated LogMonitorTests.cpp to remove the inclusion of ConfigFileParser.cpp.

Codebase simplification:

• Modified Main.cpp to use loadAndProcessJson instead of OpenConfigFile for reading the configuration file.

These changes aim to enhance the functionality and maintainability of the LogMonitor project by introducing a more robust JSON processing module.
