/*
* This program reads from the memory of an EVE Online client process.
* The memory reading approach here is based on the example from https://forum.botengine.org/t/advanced-do-it-yourself-memory-reading-in-eve-online/68
*
* In contrast to the original code, this version also supports reading from a file containing a sample of the client process.
* This allows us to repeat the reading as often we want, without having to start an instance of the game client.
* For a guide on how to save a Windows process to a file, see https://forum.botengine.org/t/how-to-collect-samples-for-memory-reading-development/50
*
* Example command line:
* dotnet run -- --source="C:\path-to-a-process-sample-file.zip" --output="C:\path\to\directory\with\write\access"
