v0.3.3 Building from source now defaults to HEADLESS and can not be set by HABITAT_BUILD_GUI_VIEWERS

[hh13g22]

Getting error:

(habitat) testunot@testunot:~/habitat-sim$ python examples/viewer.py --scene /home/testunot/habitat-sim/data/scene_datasets/habitat-test-scenes/skokloster-castle.glb
Traceback (most recent call last):
File "/home/testunot/habitat-sim/examples/viewer.py", line 19, in
from magnum import shaders, text
ImportError: cannot import name 'text' from 'magnum' (/home/testunot/miniconda3/envs/habitat/lib/python3.9/site-packages/magnum/init.py)

Reproduce:

conda activate habitat
git clone --branch stable https://github.com/facebookresearch/habitat-sim.git 
sudo apt-get update
pip install -r requirements.txt
sudo apt-get update
sudo apt-get install -y --no-install-recommends \

• HABITAT_WITH_BULLET=ON pip install . --no-build-isolation
• HABITAT_BUILD_GUI_VIEWERS=ON HABITAT_WITH_BULLET=ON pip install . --no-build-isolation

Both pip installs do not accurately install non-headless releases.
