Support memory profiles recorded with Heaptrack

[dufferzafar]

Heaptrack is a tool by KDE that generates memory profiles: https://github.com/KDE/heaptrack/

It would be great to be able to view memory profiles generated by Heaptrack in Profiler GUI.

Why not, do you know more about this tool and its format?
Currently related to heap profiling we support the dhat format coming from vagrant.
