[Feature-Request] Detect computers running macOS as interactive

[wvauclain]

Start with the why:

Some developers have mac computers and want to view visualizations.

Move to the what:

When running an example like the following on macOS, no windows currently pop up:

from depthai_sdk import OakCamera

with OakCamera() as oak:
    cam = oak.create_camera('color')
    oak.visualize(cam.out.main)
    oak.start(blocking=True)

On the other hand, if you run the program while defining the DISPLAY environment variable to a dummy value, it works.

Move to the how:

The current criteria for an interactive computer is linked below:

depthai/depthai_sdk/src/depthai_sdk/visualize/visualizer.py

Line 33 in be73fbc

IS_INTERACTIVE = 'DISPLAY' in os.environ or os.name == 'nt'

This check needs to be updated to include macOS alongside nt, since recent versions of macOS do not include an X11 server, so the DISPLAY environment variable is no longer set by default. I believe the OS name is darwin but would have to double-check that.

1.13 SDK contains refactors for visualizers, so this should be solved.
