Massive UX rewrite

- Ditch multiple libraries for progressbar, spinner, colors and replace
  with pterm
- Detect when running on terminal and disable automatically spinner
- Add support for multiple progress bars
- Huge rewrite of the configuration part. No more crazy stuff with viper
  CLI commands now correctly overrides default config file as expected
- Limit banner to be displayed on relevant parts
