This tool will translate a gettext .po file using DeepL and save the translated strings to that same file.
Before sending the message string (msgstr) to DeepL, variables eventually present in the message are replace by placeholders. This avoids the variable names beeing translated (sometimes it happened) and reduces the number of billed-chars. Both f-strings and %-interpolated variables are managed.
