Investigate and fix memory leak in human dynamics estimation code base

[yeshasvitirupachuri]

Give the code base of human-dynamics-estimation repo went through a major refactoring for V2.0.0 and the code review was not consistent, there are a lot memory leaks which sometimes lead to segmentation fault on terminating yarprobotinterface. I ran valgrind with yarp, iDynTree and human-dynamics-estimation in debug mode and the output log is stored at https://gist.github.com/Yeshasvitvs/aab49b48ba94dda1efada6e6e760ef49. valgrind is ran with the following options:

--tool=memcheck --gen-suppressions=all --track-origins=yes --show-reachable=yes --leak-check=full

In this issue we will track the details on fixing these memory leaks to improve the code.

Hi @Yeshasvitvs, the issues in the Icebox should not belong to any milestone.

If you believe to process this issue in the next to weeks, leave the milestone and move the issue to the Backlog

Segmentation fault is no longer happening, I would proceed closing this issue.
