ZM Round Calculator 2.1

2.1 has no functional changes, just did few things to make Windows Defender less picky about it, it'll still most likely prompt as a potentianlly dangerous app, nothing i can really do about it, if you have doubts you can always run it directly from source

• Full code refactor
• Fixes to logic
• Added custom arguments for things like data output for spreadsheets or predicting perfect splits for speedruns
