Update connections import to Python 3.10 version

[iMurfyD]

In Python 3.10, they changed how collections is imported. This fixes it.

For more info: https://stackoverflow.com/questions/69596494/unable-to-import-freegames-python-package-attributeerror-module-collections

This seems backwards compatible with Python 3.6 and 3.7 on my machine (Intel Macbook Pro).

  congratulations :) (62.80 seconds)

I don't see a setup.py in the repo? setup.py test output:

(missile-tid) ➜  missile-tid git:(main) ✗ python setup.py test
python: can't open file '/Users/idesjard/Documents/Planetary Surface and Spacecraft Lab/Plasma Debris Wake Research/missile-tid/setup.py': [Errno 2] No such file or directory

flake8 test output: I've made modifications to get_data.py and created a new plotting file (ianplot.py) for my own purposes. Those fail flake8, but they're not a part of this pull request.

Thanks, looks good! for the tests: they should run on github automatically, but I think because I have a free account, I need to click the button to run them manually for new contributors.
