"stty: standard input’: Inappropriate ioctl for device" when calling bdsf.process_image() on MacOS

[gabicca]

When I run some code from the Terminal of MacOS, which calls bdsf.process_image(), I get the following (partial) output:

Minimum number of pixels per island ..... : 115
Number of islands found ................. : 19
stty: 'standard input': Inappropriate ioctl for device
stty: 'standard input': Inappropriate ioctl for device

I think this comes from bdsf.functions.getTerminalSize, when it's executing struct.unpack("hh", fcntl.ioctl(fd, termios.TIOCGWINSZ, "1234"))

My hunch is that the above termios constant is not good for Macs. I'm running it on MacOS Mojave.

It'd be great if there was a workaround for this on Macs, because it's cluttering the terminal output. If anyone has a solution, please let me know.
