[Feature]: Update panda to copy-on-write and re-enable warnings

[paulf81]

Description

FLASC makes extensive use of pandas. Currently many of the scripts in flasc use warning suppressions, and many of these are warning about changes made to copies to dataframes. Beginning as an option in pandas 2 and becoming default in pandas 3, is the option to enable a copy-on-write behavior. Enabling this throughout the flasc should:

• Lower risk of bugs
• Gain performance improvements
• Remove the need to suppress warnings

Propose we should work this in soon

Sounds great! This always felt like a big challenge working with Pandas Dataframes.
