 * Convert an object's keys to camelCase.
 *
 * @param input Object (or array, when `deep`) to transform. Not mutated.
 * @param deep  Recurse into nested objects and objects nested inside arrays.
 *              Defaults to `false` (top-level keys only).
 * @returns A new value with camelCased keys.
 *
 * @example
 * camelKeys({ 'foo-bar': true });                 // => { fooBar: true }
 * camelKeys({ 'a-b': { c_d: 1 } }, true);         // => { aB: { cD: 1 } }
 * camelKeys({ 'a-b': [{ 'c-d': 1 }] }, true);     // => { aB: [{ cD: 1 }] }
