Force parse text file attachment as file when Content-Disposition: attachment header

[speller]

Please add the ability to parse the text file attachment as file when the Content-Disposition: attachment header exists for the part. I have a mail with following part configuartion:

Content-Type: text/html; name="=?UTF-8?B?Y2hlY2tfcHJpbnQuZG8uaHRtbA==?="
Content-Disposition: attachment
Content-Transfer-Encoding: base64

The createPartParserForHeaders method tries to parse this attachment as text part of the mail, so it tries to convert its encoding to utf-8 and fails, because it tries to interpret the part as 'us-ascii'. This is the attachment so it has no the encoding headers (actual file encoding can be any multibyte enoding to cause the mail parsing failure). If I set the ezcMailPartParser::$parseTextAttachmentsAsFiles to True the entire mail is parsed successfully, but it consists from attachments only, without any body text.

Suggested fix at part_parser.php:170:

if (ezcMailPartParser::$parseTextAttachmentsAsFiles === true || isset($headers['Content-Disposition']) && $headers['Content-Disposition'] === 'attachment' )

Corrected fix suggestion:

            case 'text':
                if (
                    ezcMailPartParser::$parseTextAttachmentsAsFiles === true ||
                    isset($headers['Content-Disposition']) && explode(';', $headers['Content-Disposition'])[0] === 'attachment'
                ) {
                    $bodyParser = new ezcMailFileParser( $mainType, $subType, $headers );
                }
                else
                {
                    $bodyParser = new ezcMailTextParser( $subType, $headers );
                }
                break;
