Python 3.10 workaround

[PavanKumarChaparla]

The API’s that were
developed for the manticore were based using the python versions <= 3.6 and so, it was failing
to work with python 3.10. Not a complete issue but a workaround as we donot want to disturb the previous functionalities of the previous versions we would like to mention this as a workaround to the issue. Please Use this picture to refer to the manticore.py file and make the following changes to the method referred below for earlier versions of py.
