Invert a map

Requires that the map is a simple map of keys and a list of values or a single non-map value

:duplicates which determines how duplicate values are handled:
- nil or false which is the default and means only one value is kept. Map.new/1 is used meanng the selected value is non-deterministic.
- :keep meaning duplicate values are returned in a list
- :shortest means the shortest duplicate is kept. This operates on string or atom values.
- :longest means the shortest duplicate is kept. This operates on string or atom values.
