Fix FixedRectangularBinning for StateSpaceSet containing vectors (#435)

* Fix `FixedRectangularBinning` for `StateSpaceSet` containing vectors

If a `StateSpaceSet` containing vectors is used to construct a `FixedRectangularBinning`, the element type `T` is determined as the vector type, not the underlying element type. Subsequent construction of a helper array for dealing with bounds therefore fails.

Fixed by determining the type of the underlying elements.

* bump version

* update CI file
