v2.9: VisiData crashes on launch due to missing urllib3

[jsvine]

Small description

Congrats on v2.9! Exciting to explore it! Unfortunately, one thing I noticed immediately: On a fresh install of VisiData (e.g., in a virtual environment), VisiData immediately crashes due to ModuleNotFoundError: No module named 'urllib3'. This seems to stem from loaders/unzip_http.py.

Expected result

VisiData launches successfully.

Actual result with screenshot

Traceback (most recent call last):
  File "[...]/bin/vd", line 3, in <module>
    import visidata.main
  File "[...]/visidata/__init__.py", line 110, in <module>
    import visidata.loaders.archive
  File "[...]/visidata/loaders/archive.py", line 4, in <module>
    from visidata.loaders import unzip_http
  File "[...]/visidata/loaders/unzip_http.py", line 30, in <module>
    import urllib3
ModuleNotFoundError: No module named 'urllib3'

(Running pip install urllib3 resolves this.)

Steps to reproduce with sample data and a .vd

python -m venv venv
source venv/bin/activate
pip install visidata==2.9
vd .

Additional context

• VisiData 2.9
• Python 3.10
• MacOS

Thank you so much @jsvine! I am so grateful that you caught it and filed an issue so quickly. I just shipped v2.9.1. urllib3 is for now an optional dependency.
