feat(nodes): add RangeOfSizeInvocation

Browse Source 
The `RangeInvocation` is a simple wrapper around `range()`, but you must provide `stop > start`.

`RangeOfSizeInvocation` replaces the `stop` parameter with `size`, so that you can just provide the `start` and `step` and get a range of `size` length.
