1.1.2 - Minor bugfixes

Found a few little bugs that needed squashing.

• Fixed a mismatch in redpy-write-family-locations between the default file name and the docstring
• Fixed a rare divide by zero issue in calculation of frequency index (should return np.nan if denominator is exactly 0)
• Fixed chained assignments for a few pandas DataFrames (previous pipelines were complaining that these won't work in pandas 3.0)
