Cleanup, Arguments

[ghost]

• Rewritten the Program.cs to get it clean and readable
• Rewritten the usage section
• Added ArgumentParser (!!! ATTENTION !!! some arguments have changed)
  • ProgramArgs contains all possible parameters for the command line
    Feel free to add some ;)

My personal thoughts:

• I'd heavily prefer to use an existing library, rather than writing our own ad-hoc parsing. If we were going to do it ourselves then I'd also try avoid reflection, as it is unnecessary when you know what all the possibly inputs are.
• Migrate to System.CommandLine #234 has attempted a similar thing with a different library, but I don't like the way that it represents the options either, and would personally be partial to using CommandLineParser instead.
• I think its too late in the project to change existing command-line arguments. We've had enough issues with newbies who got confused by the move to a .NET Core Framework-Dependent Deployment, and there seems to be a lot of third-party documentation (forum posts, YouTube videos, etc.) that I would rather not break if there is no reason to.
• The Pull Request is still a decent amount of work done in good faith, and given the timing I'd be happy to flag it for Hacktoberfest if that's your thing.

I'm gonna close this in favor of #234 as per @yaakov-h's thoughts.
