Cross-platform host or CLI version

[alexwnovak]

I play roms on my Mac and would love to use the randomizer there. I see the Lib project targets .NET Standard 2.0 (and it compiles fine with the .NET 6 CLI on my Mac). The WPF host is obviously an issue. I propose either a cross-platform GUI host (MAUI), or an easier step, a cross-platform Console app. I was able to hack together an example project on my Windows VM and it works fine (it crashes with an IndexOutOfBounds exception when I build/run on my MacBook Pro, but I don't know why).

I'm sure I can make this work for me, but would love to contribute it back for others. Is this something you'd want in this project?
