Issue running ska distance with pandas >=3

[kristyhoran]

Hello @johnlees !!

This morning i created a new conda env and installed ska 0.5.1... When i ran ska distance I got this error

TypeError: NDFrame.fillna() got an unexpected keyword argument 'downcast'

When i looked into the environment setup and compared to an older one (created last month) with ska 0.5.1 - the pandas version in the new one was 3.0.0 were as the one the worked was pandas 2.3.3. I downgraded pandas to v2.3.3 and the error was resolved.

Just thought someone should bring this potential issue to your attention. I have now pinned pandas to < 3.0.0 in my envs to prevent the issue.

Cheers
Kristy

Thanks for reporting this. Do you have the full error trace you could share? I can't actually see where we use this in the code so not sure what I would need to fix (and ideally we can make it so that it works with a 'typical' install without pinning)
