Bumps ex_slop from 0.4.4 to 0.4.5.

Release notes

Sourced from ex_slop's releases.

v0.4.5

Fixed

• IdentityPassthrough no longer flags map/struct projections (%{a: a} -> %{a: a} drops extra keys). A non-exhaustive identity case is still reported, but the message now notes that it raises CaseClauseError on unmatched values whereas returning the value directly does not.
• ReduceMapPut no longer flags reductions whose key or value reads the accumulator (e.g. summing duplicate keys), since Map.new/2 cannot express them.
• PreferEnumSlice no longer flags Enum.drop/2 |> Enum.take/2 with negative literal arguments, which Enum.slice/3 does not treat the same way.
• FlatMapFilter now only flags callbacks whose singleton list holds the argument unchanged; [x * 2] is a transformation that Enum.filter/2 cannot replace.
• IdentityMap now suggests Enum.to_list/1 for inputs that may not be lists (ranges, streams, MapSets), since removing the call would change the return type.
• SortThenReverse no longer flags Enum.sort_by/2 |> Enum.reverse/1: sorting is stable, so the reverse changes the relative order of equal keys while Enum.sort_by(fun, :desc) preserves it.
• WithIdentityElse no longer treats map/struct patterns as identity. A non-exhaustive identity else is still reported, but the message now notes that it raises WithClauseError on unmatched values whereas removing it would return them as-is.
