Translate Adapter for multi-column csv

[challet]

Hello!

• Type: new feature

In raising this pull request, I confirm the following (please check boxes):

• I have read and understood the Contributing Guidelines?
• I have checked that another pull request for this purpose does not exist.
• I wrote some tests for this PR.

Small description of change: adding a multi-column csv adapter for the translations.

• CSV example (blank spaces added for readability):

#ignored;     en_US;  fr_FR;   es_ES
label_street; street; rue;     calle
label_car;    car;    voiture; coche
label_home;   home;   maison;  casa

• PHP example :

// the constructor is inherited from Phalcon\Translate\Adapter\Csv
$titles_translater = new Phalcon\Translate\Adapter\MultiCsv([
    'content' => "{$config->langDir}/titles.csv"
]);
$titles_translater->setLocale('es_ES');
echo $titles_translater->query('label_home'); // string 'casa'

It might remain a check to be done about the ArrayAccess interface (inherited from Phalcon\Translate\Adapter\Csv)

Looks like the last commit (upgrading codeception) fixed this error but broke something else. Help please.
