Get keys of value in object, like Array.indexOf().

const keysOf = require('@extra-object/keys-of');
// keysOf(<object>, <search value>, [target=[]], [at])

var a = {r: 'R', o: 'O', b: 'B', e: 'O'};
keysOf(a, 'o');
// ['o', 'e']
keysOf(a, 'o', ['a', 'b']);
// ['a', 'e', 'o', 'e']
keysOf(a, 'o', ['a', 'b'], 1);
// ['a', 'o', 'e']
