feat: OLE CF and VBA modules implemented

[davidmagnotti]

OLE CF (Object Linking and Embedding Compound File) format is a file format used for legacy Microsoft Office files, such as documents, workbooks, presentations, and others. It's also used with Visual Basic for Applications (VBA) which is known more commonly as Office macros.

I've implemented two modules for parsing OLE CF files and VBA. I've also expanded the dump command to allow dumping of file metadata such as stream metadata (OLE CF) and macros (VBA).

An example of how you could use this to identify the use of auto-execute macro method names like "Document_New":

import "vba"

rule detect_document_new
{
    condition:
        for any module in vba.module_code : (
            module matches /document_new/i
        )
}
