Description

Per discussion https://github.com/apache/arrow/pull/5195#issuecomment-528425302

We may use API this way:

RangeEqualsVisitor visitor = new RangeEqualsVisitor(vector1, vector2);
vector3.accept(visitor, range)

if vector1/vector2 are say, StructVector}}s and vector3 is an {{IntVector - things can go bad. we'll use the compareBaseFixedWidthVectors() and do wrong type-casts for vector1/vector2.
