Inconsistent behavior with Arrays

[cinderblock]

const camelcaseKeys = require('camelcase-keys');

At top level, array members are turned into array elements.

(a = [{test_one: 1}]).test_two = {}; a;
// [ { test_one: 1 }, test_two: {} ]
camelcaseKeys(a);
// [ { testOne: 1 }, {} ]

At lower levels, array members are lost.

(o = {deep: [{test_one: 1}]}).deep.test_two = 1; o;
// { deep: [ { test_one: 1 }, test_two: 1 ] }
camelcaseKeys(o, {deep: true});
// { deep: [ { testOne: 1 } ] } }

I realize this is bad practice.
However, that this library mangles them and, in particular, inconsistently is I think problematic.

Proposed solution

map-obj already has the ability to handle Arrays.
Simply remove the extra function at module.exports and export camelCaseConvert directly.

Side note

Doesn't map-obj already have a caching mechanism?
It seems a little redundant to me to have a caching layer in this package.
Maybe I'm missing something?

Only nested arrays. Not a top-level array.

No

Your use-case is very obscure, but I'm willing to merge a good PR from anyone that includes tests.

I'm not following what you're saying. It seems to support them to me:

const mapObj = require('map-obj');
console.log('mapped:', mapObj(['test']));
// mapped: [ 'test' ]

Forgive my persistence, but it sure seems to https://github.com/sindresorhus/map-obj/blob/master/index.js#L17-L23 Am I missing something?

On that subject, any thoughts on sindresorhus/map-obj#15
