feat(statusbar) add menu for language and model

[diegomarne]

I have added two new menus in the status bar:

1. "Language" menu: It contains all the supported languages by whisper. I get all these languages from an array of whisper library. If you pass some language from the command line, these languages will listed on the top list. The default option selected for this menu is "auto-detect".
2. "Models" menu: Contains all the whisper available models. It marks as selected the default base model or the model passed though the command line

I developed it before 7e1324b commit, so I adapted it to these new changes.
I have developed it for two reasons:

1. In my daily life, I speak three languages (spanish, catalan and english) i was constantly stopping and restarting the script to switch between languages and sometimes between whisper models.
2. I want to show this tool to a friend thant has 0 knowledge about IT. I considere make it as easy as possible for him so he wouldn't need to type command lines.

I hope that this will be useful.
