Issue with funky flag

[will09122000]

I cannot create a funky shape, other shapes appear to work as expected. I believe the example in the readme has a typo with an extra bracket? Here's the command I'm trying and the error I'm getting:

gfbin --funky "[[True, False], [True, False], [True, False], [True, True]]" -z 14

File "/Users/---/.pyenv/versions/3.11.2/bin/gfbin", line 8, in <module>
    sys.exit(main())
             ^^^^^^
  File "/Users/---/.pyenv/versions/3.11.2/lib/python3.11/site-packages/gfthings/gfbin.py", line 150, in main
    bin = FunkyBin(list(reversed(funky_expr)), z,
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: FunkyBin.__init__() got an unexpected keyword argument 'half_grid'

I'm using an Apple Silicon Mac.
