text: Title: Freetype version error
  Body: When trying to run faceswap.py (on macOS Mojave), the following error occurs:
  
  `Traceback (most recent call last):
    File "/Users/user/faceswap/faceswap.py", line 5, in <module>
      import lib.cli as cli
    File "/Users/user/faceswap/lib/cli.py", line 17, in <module>
      from lib.utils import FaceswapError, safe_shutdown
    File "/Users/user/faceswap/lib/utils.py", line 18, in <module>
      import cv2
  ImportError: dlopen(/Users/user/anaconda3/envs/faceswap/lib/python3.6/site-packages/cv2.cpython-36m-darwin.so, 2): Library not loaded: @rpath/libfreetype.6.dylib
    Referenced from: /Users/user/anaconda3/envs/faceswap/lib/libopencv_freetype.4.1.dylib
    Reason: Incompatible library version: libopencv_freetype.4.1.dylib requires version 24.0.0 or later, but libfreetype.6.dylib provides version 23.0.0`
  
  This happens regardless of whether I try to use the GUI or command line. I'm not sure, but it seems that freetype is an engine or displaying text. If this is the case, why do I need it in order to use the command line? How can I update freetype?
