Create a function call stack

[saphal1998]

• Investigate which DS can do this best (Probably, stack 😆 )
• Construct the event stack at a particular ts
• Generalise it for the entire duration of profiling

TBD : 2nd point, needs more discussion

Done! 💥 Results on time-dict branch. The format is

timestamp : [
 list of stackFrames (in order with the deepest element first)
]

for all timestamps in our samples array

There is clearly an implementation detail flaw in the timeStampEvents.json file, but I do this call stack will be very useful!

There is no need to do this, can be achieved through Lighthouse parser code. All we needed to do was to convert the Hermes Profile into ProfileChunks objects.
