python decoder example

Description of problem:
When using qpid python client, decoding an AMQP message takes considerably longer time than using c++ client

Version-Release number of selected component (if applicable):
python-qpid-1.35.0-5.el6.noarch
qpid-cpp-client-1.36.0-15.el6.x86_64 or qpid-cpp-client-1.36.0-20.el6_10.x86_64

How reproducible:
Always

Steps to Reproduce:
Use the attached scripts with ~11mb message ("sample_message") in the same directory and compare the times (content print out was edited out):

[root@bvassova-mrg decode]# time python PythonAmqpMsgDecoder.py 
real	6m50.005s
user	6m47.138s
sys	0m0.301s

[root@bvassova-mrg decode]# time ./CppAmqpMsgDecoder
File size is 11759031 bytes.

real	0m1.836s
user	0m1.607s
sys	0m0.134s

with uncommented printing out the file content (for fairness) cpp decoder got
real	0m3.407s
user	0m1.846s
sys	0m0.173s


Actual results:
The result time should be approximately similar

Expected results:
The python decoder is considerably slower than c++ decoder
