feat: add option to only draw whitespace if it is within selection (#1312) 

* refactor: remove sort_positions usage
* refactor: move draw conditional to has_any_selection and other changes
  - snake case (sssss)
  - break after finding selection
* fix: typo of config plugins
* fix: do check for show selected only properly
* feat: only draw within selection per substitution
* `drawwhitespace`: Make `show_selected_only` work properly
