Use optparse-applicative for CLI better

[kamil-adam]

• Use alternative for Input https://github.com/pcapriotti/optparse-applicative#alternative
• Use auto https://github.com/pcapriotti/optparse-applicative#regular-options
• Use flags https://github.com/pcapriotti/optparse-applicative#flags and don't use any switch
• Use verbose flag for Logs
• Use commands for Langs https://github.com/pcapriotti/optparse-applicative#commands
  • https://www.fpcomplete.com/haskell/library/optparse-applicative/
• Use disambiguate pref
• Use showHelpOnError and showHelpOnEmpty
• Split parser to many, small option parsers
• Use alternative for emit https://www.fpcomplete.com/haskell/library/optparse-applicative/
• Use version from git https://www.fpcomplete.com/haskell/library/optparse-applicative/
• Use records https://nanonaren.com/2014/08/09/choices-command-line-parsers-2/

The perfect pattern is https://doc.rust-lang.org/rustc/command-line-arguments.html

• emit
• print

We have many languages. And some languages use special flags. So we should use lang-parameter as Commands.
We also have to add documentation for all languages and parameters
