Relax dependency requirements?

[maresb]

Do we need the >=2.0 Pandas requirement, or is it just a matter of never having tested with 1.x? I'm asking because 2.0 is relatively new, and there are likely a lot of projects [looks over shoulder] that haven't yet migrated 1.x → 2.x.

I think pandas<2 should be fine, I just didn't test it.

Is this relevant anymore? I think we should be pushing toward adoption of pandas 2.x at this point.

In general I agree, but for me personally, not all packages I'm using are 2.x compatible.
