tcpdi_parser 1.0 fixes

tcpdi_parser.php.txt
In the above parser, I found and fixed a few issues when I was attempting to create a PDF with embedded PDFs.

1. Line 555 was inserted because there could be an odd number of characters in the row ($xrefcrs[1][3][0] - see line 528), so that $row[1] could be undefined.
2. Lines 623, 624, and 626 were inserted because $row[$i] was not always set or defined.
3. Lines 814-819, and 821 were inserted because the offsets were not always within the boundaries of $data, causing the data to be corrupted on a subsequent loop. The "@" was suppressing these errors.

Hope this helps? Please let me know if there are any questions.
