Find smallest and largest entries.
function rangeEntries(x, fc, fm)
// x: lists
// fc: compare function (a, b)
// fm: map function (v, k, x)const xlists = require('extra-lists');
var x = [['a', 'b', 'c', 'd'], [1, 2, -3, -4]];
xlists.rangeEntries(x);
// → [ [ 'd', -4 ], [ 'b', 2 ] ]
xlists.rangeEntries(x, (a, b) => Math.abs(a) - Math.abs(b));
// → [ [ 'a', 1 ], [ 'd', -4 ] ]
xlists.rangeEntries(x, null, v => Math.abs(v));
// → [ [ 'a', 1 ], [ 'd', -4 ] ]
