handle_one_request fails with error: AttributeError: module 'collections' has no attribute 'Callable'

handle_one_request fails with error:

Exception occurred during processing of request from ('192.168.100.14', 50518)
Traceback (most recent call last):

I am using python3.10

Suggesting this fix:

--- a/pyicap.py
+++ b/pyicap.py
@@ -515,7 +515,7 @@ class BaseICAPRequestHandler(StreamRequestHandler):
                 raise ICAPError(404)

That suggested change works for Python 3.10.
