i want for solutions() etc to NOT duplicate the >1 multiplicity solutions

[ofloveandhate]

they should return just ONE representative for each multiplicity class.

[ofloveandhate]

the to_dataframe function already offers an option to do this: merge_multiplicities=True

[ofloveandhate]

Addressed in #305 — merge_multiplicities (default True) on solutions() and the finite category accessors (real_solutions, finite_solutions, ...), so a multiplicity-m solution returns a single representative. Pass merge_multiplicities=False for all m coincident copies. Folded into the C++ SolutionsWhere predicate (where the clustering lives), matching to_dataframe's existing default.
