Labels incorrects

```
SPREADSHEET_EXCEL_READER_TYPE_LABEL in excel file version
SPREADSHEET_EXCEL_READER_BIFF8 are not readed correctly.

In BIFF8 a encoding byte was added for LABEL.
row (2 bytes) + col (2 bytes) + string length (2 bytes) + encoding (1 byte).
Encoding byte is equal to 0 (CP1252) or 1 (UTF16).

------------------------
Old code (in line 1521):
------------------------

case SPREADSHEET_EXCEL_READER_TYPE_LABEL:
$row = ord($data[$spos]) | ord($data[$spos+1])<<8;
$column = ord($data[$spos+2]) | ord($data[$spos+3])<<8;
$this->addcell($row, $column, substr($data, $spos + 8, ord($data[$spos
+ 6]) | ord($data[$spos + 7])<<8));
break;

-------------
Replace code:
-------------

case SPREADSHEET_EXCEL_READER_TYPE_LABEL:
$row = ord($data[$spos]) | ord($data[$spos+1])<<8;
$column = ord($data[$spos+2]) | ord($data[$spos+3])<<8;
$strlen = ord($data[$spos + 6]) | ord($data[$spos + 7])<<8;
if ($version == SPREADSHEET_EXCEL_READER_BIFF8) {
$encoding = ord($data[$spos + 8]);
if ($encoding) {
$string = $this->_encodeUTF16($string);
}
$string = substr($data, $spos + 9, $strlen);
$this->addcell($row, $column, $string);
}
else {
$string = substr($data, $spos + 8, $strlen);
$this->addcell($row, $column, $string);
}
break;

Start at the LABEL record handling around line 1521 and inspect how BIFF8 records are parsed. Reproduce the problem with the attached “mes prospects.xls” file, then verify that LABEL cells are read correctly for BIFF8 without regressing older Excel versions.
