    net-p2p/py-ed2k-tools: add rudimentary support for TAG_TYPE_BLOB
    
    While most common eDonkey2000's .part.met tags are integers and
    strings, there could be other data embedded in them, like binary
    data blobs.  Ignore (skip) them for now rather than choking on.
    
    While here, use a better way to detect if supplied argument is
    a directory.
