pandas warning about .apply(sum)

TAMS/tams/core.py

Line 799 in 0b74da8

area = time_groups[["area_km2", "area219_km2"]].apply(sum)

May be able to just use .sum() instead. Or pandas suggests switching to .apply('np.sum') to keep the current behavior.

Also seeing a corresponding warning with this in some envs:

numpy/core/fromnumeric.py:86: FutureWarning: The behavior of DataFrame.sum with axis=None is deprecated, in a future version this will reduce over both axes and return a scalar. To retain the old behavior, pass axis=0 (or do not pass axis)

which seems to be really a pandas 2 thing.
