Implement RangeCondition using set operations

Although `net.imglib2.RangeCondition` is used by `PointSetParser`, we do not need those classes yet in imagej-ops. `RangeCondition` is not used anywhere else, so it may be better to hold off on its implementation till more set functions exist within ImageJ OPS.

`RangeCondition` is fundamentally a set inclusion test, but limited to a linear set defined by start, end, step parameters. Generalizing this logic to have "element" and "contains" set operations, together with a linear set implementation, would solve the `RangeCondition` use case in a far more general way.

No files, tests, or entry points are named. Start by reviewing the proposed element and contains set operations and the linear-set implementation, then determine how they would cover RangeCondition's use case in PointSetParser; done means the generalized set logic replaces that use case without requiring unrelated classes.
