Subject: [PATCH v4 0/6] Add support for Firefox's gecko profile format

This patch series adds support for Firefox's gecko profile format.
The format is documented here [1].

I have incorporated several changes based on feedback from the
previous version of the patch.

Changes in v3:
- Implemented object-oriented programming (OOP) approach for Thread and Sample
  to improve code organization and maintainability.
- Enhanced user experience by introducing argparse for changing color settings
  of user and kernel symbols during execution.
- Ensured proper module encapsulation by adding imports wherever necessary.
- Improved code readability by adding descriptive comments and type annotations.

These changes focus on adopting OOP principles, enhancing user interaction with argparse,
and making the code more readable with comments and type information.

TODO:
- use cpu_mode to determine the category instead of finding it from symbol name.
- Write a test.
- add direct execution command for this script under script/python/bin directory.

Committer Testing:
- Tested with a perf.data file generated for single and multiple cpu
  cores enabled.
- Uploaded the stdout into profiler.firefox.com and verified the
  output.
- Verified the output with the output generated by the existing
  script as mentioned here [2].
Method:
- perf record -F 99 -a -g -- sleep 5
- perf script firefox-gecko-converter.py > output.json
- upload output.json to profiler.firefox.com
