Pip install hangs due to broken overlay download

[mdarnold1]

Install hangs on downloading overlays. Inspecting the links shows that at least some are broken, but the first file attempted (and many others) can be downloaded manually. Would be helpful to have instructions for a workaround until this is fixed.

Also affects https://pypi.org/project/pynq-compute-labs/ - reporting here because I can't find a git for that and I assume the projects are linked.

pip install with --no-build-isolation due to #32 (dependencies installed separately)

with -v gets stuck here: copying pynq_alveo_examples/notebooks/4_building_and_emulation/1-building-with-vitis.ipynb -> build/lib/pynq_alveo_examples/notebooks/4_building_and_emulation
