Suggested rule title

Bounded array range should start from 0

Rule description

This rule would pick up on cases when a bounded array variable has a non-zero start when instantiating.

var
  Foo: array[1..5] of String; // non-compliant
  Bar: array[0..4] of String; // compliant

Rationale

Since RTL list always start from 0 index, there's no good reason for a bounded array range to start from non-zero. To make looping through such as arrays uniform, we should always start from zero.
