fix: Implemented forwarder executable (#1308)

Fixes random .NET plugin crash caused by the console window being freed on the same process. ### Problem description Sometimes when launching from the explorer ImHex crashes ### Implementation description We've implemented a launcher to avoid freeing the std streams, that generated the bug. ### Screenshots N/A ### Additional things Blame windows console subsystem
