[BUG]matplotlib 3.9 broken dependency

[ljw20180420]

As in open2c/cooltools#533, please also fix this for coolpuppy.

I think if you upgrade cooltools it should fix coolpuppy, doesn't it?

[ljw20180420]

No. My cooltools are the newest version 0.7.1. My coolpuppy is the newest version 1.1.0. However, the error persists.

Call result.infer_objects(copy=False) instead. To opt-in to the future behavior, set `pd.set_option('future.no_silent_downcasting', True)`

I use the command

plotpup.py --input_pups file.clpy -o file.pdf

As you can see, the error comes from cooltools. coopuppy doesn't run this command directly.

Yes! You are right. So cooltools does not fix the bug complete in 0.7.1? I will close this and open a new one in cooltools.
