[NFR]: Implement additional methods in class \Phalcon\Helper\Arr.

[TimurFlush]

Hello!

In my opinion, the Phalcon\Helper\Arr helper lacks two important methods:

1. Phalcon\Helper\Arr::blackList() - is a method that removes the specified keys from the passed array. In its own way it is the opposite copy of the Arr::whiteList()

2. Phalcon\Helper\App::map()- is the alias of \array_map()

P.S I will create PR as soon as i can

1. This could be helpful

2. I wouldn't vote for adding a method that is creating an alias only. It will create unnecessary overhead and would advice just to use the native array_map.

Any additional methods should go to 4.1 release otherwise we break semver.

Then I wonder why there are methods Arr::chunk() and Arr::filter()?

Arr::filter() was introduced to reduce the common code in the class. As you will see it is used in quite a few methods there so...
