Change range max parameter to be exclusive

[aleclarson]

As suggested in sodiray/radash#331

Why is the range function in Radash max inclusive rather than max exclusive? The docs say that the function is a hat tip to the Python implementation by the same name, so why don’t they function identically? It makes it hard to iterate over an array without making the max value arr.length - 1.

This also applies to the list function, according to @torgesla's comment in that same issue.
