Consider libraries for commandline parsing

[baseTwo]

The CommandLineParser Nuget package could a better solution to parse command line arguments. Consider using it in the PackageCLI projects, since it worked well in the demo project used in issue #323

Consider breaking up the cli into verbs (e.g. cql2elm, elm2csharp, compile, resource, etc)

Please also consider https://learn.microsoft.com/en-us/dotnet/standard/commandline/, since that's what we are using in the CAR factory project.

Another consideration is Spectre.Console, which supports not only parsing command line args, but also advanced console output. This library is also used in Dumpify
