IMPORT_FROM only takes one LOAD_ATTR

[gstarnberger]

Copied from: http://code.google.com/p/unpyc/issues/detail?id=9

decompiling a program that uses:

import a.b.c.d as e

will fail, because the code expects no more then one LOAD_ATTR after a IMPORT_FROM statement.

A work around is to add the following, up to the number of LOAD_ATTR lines you are seeing - I don't currently see a way to tell unpyc to accept any number of them. Starting at line 189 in Parser.py, add:
import_as ::= IMPORT_NAME LOAD_ATTR LOAD_ATTR designator
import_as ::= IMPORT_NAME LOAD_ATTR LOAD_ATTR LOAD_ATTR designator

etc, etc, etc

Yes, I know this doesn't fit the 0,1,n pattern, but it is a quick fix.

Later uncompyle2/uncompyle6 handle this with a list. See https://github.com/rocky/python-uncompyle6/blob/master/uncompyle6/parser.py#L391
