Fix: Obtain certificate info when "," contained inside Quotation marks.

[celli33]

When comma is found inside certificate data the function LSNepomuceno\LaravelA1PdfSign\Sign\ValidatePdfSignature::processDataToInfo throws an Undefined array key 1 because of:

$data = explode(', ', $data);

It can be removed by using preg_split like:

/** it allows to split  by "," except when "," inside of quoutes */
$data = preg_split('/\s*,\s*(?=(?:[^"]*"[^"]*")*[^"]*$)/', trim($data));

For example:

$data = "emailAddress = [email protected], street = "AV. HIDALGO 77, COL. GUERRERO", postalCode = 06300"

the function: explode(", ", $data) will return and array separated in [["street" => "AV. HIDALGO 77"], [" COL. GUERRERO"]].

When expected is: [["street" => "AV. HIDALGO 77, COL. GUERRERO"]]
