          Arguments
          ---------
          value : ?
              A value to solve in combination with the given filter.
          filter_ : dataql.resource.SliceFilter
              An instance of ``SliceFilter``to solve with the given value.
  
          Example
          -------
  
          >>> from dataql.solvers.registry import Registry
          >>> registry = Registry()
          >>> solver = SliceSolver(registry)
          >>> solver.solve([1, 2, 3], SliceFilter(1))
          2
          >>> solver.solve([1, 2, 3], SliceFilter(slice(1, None, None)))
          [2, 3]
          >>> solver.solve([1, 2, 3], SliceFilter(slice(0, 2, 2)))
          [1]
          >>> solver.solve([1, 2, 3], SliceFilter(4))
