The V5 directory and filename table parsing had checks in to make sure we hadn't read past the end of the line tabel prologue. Since previous changes to the data extractor class sure we never read past the end, these checks are now redundant, so this patch removes them.

There is still a check to show that the whole prologue remains within the prologue length, which is now hit instead.
