Range Types (T[X:Y]) for TypeScript

A Range Type is a type that produces a new tuple or array type that derives from T by dropping the excess ordered elements of T outside of the range starting at offset X (inclusive) through offset Y (exclusive).

A Range Type is denoted using a : operator in what would otherwise be an Indexed Access Type:

type T = [1, 2, 3][0:2];
