### What happened?
I get the following error:
```
in test_size_of_weakref
print(objsize.get_deep_size(oref))
File ".../python/.eggs/objsize-0.5.2-py3.8.egg/objsize.py", line 235, in
get_deep_size
return sum(map(get_size_func, it))
File ".../python/.eggs/objsize-0.5.2-py3.8.egg/objsize.py", line 91, in

filter_func(o)}

return not isinstance(o, type)
ReferenceError: weakly-referenced object no longer exists
```
when running the following test:
```
import unittest
import objsize
import weakref
import threading
class Foo(list):
pass
class WeakRefTest(unittest.TestCase):
def test_size_of_weakref(self):
wait_event = threading.Event()
o = Foo("SuperDuper")
oref = weakref.proxy(o, lambda value: wait_event.set())
del o
wait_event.wait()
objsize.get_deep_size(oref)
```
