 - WinRT OCR: this will work on Windows 10 or later if winocr (`pip install winocr`) is installed. It can also be used by installing winocr on a Windows virtual machine and running the server there (`winocr_serve`), and installing requests (`pip install requests`) and specifying the IP address of the Windows VM/machine in the config file ("w" key)
