The stack has been created for storing func and dso from the callchain.
The sample has been added to a specific thread. It first checks if the
thread exists in the Thread class. Then it call _add_sample function
which is responsible for appending a new entry to the samples list.
Also callchain parsing and storing part is implemented. Moreover removed
the comment from thread.

The intern_stack function is responsible for retrieving
or creating a stack_id based on the provided frame_id and prefix_id.
It first generates a key using the frame_id and prefix_id values.
If the stack corresponding to the key is found in the stackMap,
it is returned. Otherwise, a new stack is created by appending
the prefix_id and frame_id to the stackTable. The key
and the index of the newly created stack are added to the
stackMap for future reference.
The _intern_frame function is responsible for retrieving or
creating a frame_id based on the provided frame string. If the frame_id
corresponding to the frameString is found in the frameMap, it is
returned. Otherwise, a new frame is created by appending relevant
information to the frameTable and adding the frameString to the string_id
through _intern_string.
The _intern_string function will gets a matching string, or saves the new
string and returns a String ID.

information
The final output will now be presented in JSON format following the Gecko
profile structure. Additionally, the inclusion of PRODUCT allows easy retrieval
of header information for UI.
Furthermore, CATEGORIES have been introduced to enable customization of
kernel and user colors using input arguments. To facilitate this functionality,
an argparse-based parser has been implemented.
Note: The implementation of threads will be addressed in subsequent commits
for now I have commented it out.

This commit introduces new classes and conversion functions to
facilitate the representation of Gecko profile information. The new
classes Frame, Stack, Sample, and Thread are added to handle specific
components of the profile data, also link to the origin docs has been
commented out.
Additionally, Inside the Thread class _to_json_dict() method has been
created that converts the current thread data into the corresponding
format expected by the GeckoThread JSON schema, as per the Gecko
profile format specification.

The script takes in a sample event dictionary(param_dict) and retrieves
relevant data such as time stamp, PID, TID, and comm for each event.
Also start time is defined as a global variable as it need to be passed
to trace_end for gecko meta information field creation.
