Introduce the `Input` class

Imagine this case:

$ php foo.php

where foo.php is a program that reads from STDIN. It works perfectly with Hoa\Console.

Now, imagine this other case:

$ echo "foo\nbar" | php foo.php

STDIN will contain foo and bar but the Hoa\Console\Cursor —for instance— will no longer work since it reads from STDIN too.

The idea is then to close STDIN (aka php://input) and open /dev/tty, which is the real standard input in this case.

So, to address these needs, we introduce the Hoa\Console::getStdin method that is a helper to choose the appopriate standard input. We also change the Hoa\Console::advancedInteraction behavior: 👷 stty uses the -f option to specify /dev/tty instead of the default standard input. However, on Linux, this is -F. I don't know how to address this right now (I mean: Making something cross-platform).

Finally, all Hoa\Console's classes that were using STDIN directly are now using Hoa\Console::getStdin.

New title

Actually, since #55, this PR has taken a new path. We also introduced an Input class. And it considers whether to use Hoa\File\Read('php://stdin') as the default input, or Hoa\File\Read('/dev/tty') in case the former has been closed. This is a basic wrapper.
