Thanks for the fixes @marscher !

what is the minimum pandas version required for this? Does it work with 1.5.x still?

I've added some backward compatibility code for reading old unit suffixes. Currently it only replaces the (used by weldx schema examples) suffix for seconds "S". I am not aware of any other units used in the past by weldx. To ensure we can still load old files with the new version, we should probably complete this list.

[marscher]

Sorry I misinterpreted your question. I did not check, if it works with old Pandas versions. Is this a requirement or can we just pin a minimum version?

[marscher]

I've tested pandas-1.5 with Python-3.11 locally and all tests pass.

[marscher]

The CI failures are unrelated to my changes. I think this one is ready to go.

If you tested it with 1.5 I am fine with pinning minimum pandas version >=1.5. 😊 I will update the CI to test for that later as well
