Unclear error when reading trace that would require `EXTENDED_OBJECTS_ENABLED` to be set

[valentin-seitz]

When having a trace with some object identifier bigger than uint16_t e.g. 65535 the current behavior of paraver and wxparaver is to be unable to read the record:

Error reading event record.

I think it would be nice, to maybe check if the user is trying to load a trace that has more than 65535 objects (Could be done easily when parsing the row file) and just exit with a meaningful error informing the user about the --enable_extended_objects configure flag.
