'<=' operator does not distinguish 0 and null, should be '<=='

[gasp]

let's consider this rule, looking for values between or equals 0 and 1

const rule = { '<=': [0, { var: 'data' }, 1] };

with data being 0, it works

const zeroInput = { data: 0 };
const zeroArrayInput = { data: [0] };
jsonLogic.apply(rule, zeroInput); // returns true
jsonLogic.apply(rule, zeroArrayInput); // returns true

with data being null, this is wrongly interpreted

const nullInput = { data: null };
jsonLogic.apply(rule, nullInput); // returns true, whereas it should be returning false
