text: Title: [Bug] Text input via cat and multiple lines
  Body: ### Describe the bug
  
  When feeding multiple lines of text using cat into the tts command line tool, tts creates long pauses after a line break.
  
  ### To Reproduce
  
  1. Write some text with line breaks into demo.txt
  2. Execute tts --text "$(cat demo.txt)" --out_path demo.wav --model_name whatever/model
  
  ### Expected behavior
  
  It shouldn't make a pause when just a simple line break is found.
