Compare two ientries.

Similar: compare, isEqual.

function compare(x, y, fc, fm)
// x:  ientries
// y:  another ientries
// fc: compare function (a, b)
// fm: map function (v, k, x)

const ientries = require('extra-ientries');

var x = [["a", 1], ["b", 2]];
var y = [["a", 1], ["b", 2], ["c", 3]];
ientries.compare(x, y);
// → -1

var y = [["a", 1], ["b", 2]];
ientries.compare(x, y);
// → 0

var y = [["a", 1], ["b", -2]];
ientries.compare(x, y);
// → 1

ientries.compare(x, y, (a, b) => Math.abs(a) - Math.abs(b));
// → 0

ientries.compare(x, y, null, v => Math.abs(v));
// → 0
