PIDL fix for using external types with wireshark backend

List,

Please review this patch to pidl.

Basically,  we need to process the wireshark conformance file BEFORE
we process the idl file since this file may define external types
and set the alignment for them (using the TYPE directive).
Otherwise pidl will default all external types to use 4byte alignment
which breaks (much more often) on NDR64

Subject: [PATCH] In the PIDL wireshark backend, we define external types in the conformance
 file using the TYPE directive.
 If we declare external types here, we must parse this file before we process
 the IDL file, or else these external types will all default to 4byte padding
 (pidl assumes all unknown types are 4byte aligned).

Make sure we read the conformance file and create these new types before
we parse the idl file.
