I don't manipulate the CSV file anymore, but you can set the prefered eol now which defaults to \n.

Decided to simplify the API again by removing the string extenstion tr.

This makes more sense if we want to use multiple localization libraries.

Moved string_ext to the example folder if you want to use it.

• added CsvLocalizations.instance to avoid the need for a BuildContext
• added String extension getter 'tr'

• use \n as default eol but replace \r\n with \n before parse
• improve README
• add multiline example

• update README

• add rationale to README
