String fetch functions

ASL has 4 types of strings:

• fixed length (4 bytes)
• variable length (length (4 bytes) + string (var))
• pascal (length (1 byte) + string (var))
• unicode string (length (4 bytes) + null-terminated unicode string (var)

Definition at line 115 of file kis_asl_reader_utils.h.

{
    QByteArray data = psdreadBytes<byteOrder>(device, length);
 
    if (data.size() != length) {
        QString msg = QString(
                          "Failed to read a string! "
                          "Bytes read: %1 Expected: %2")
                          .arg(data.size())
