PR Description Should Include

Add Windows network monitoring: shows bytes sent/received (KB/s) and the related funny moods.

• What: Add Windows network monitoring and related moods
• Why: This feature is listed in the “awaiting contributions” section, and monitoring network speed is also a fundamental part of system resource tracking.
• How: Uses GetIfTable, 3s sampling, 64-bit accumulation + wrap-around handling.
• Testing: use g++ -Iinclude src/main.cpp -o SysMood.exe -liphlpapiand run the .exe. file

!! Important: You must compile with g++ -Iinclude src/main.cpp -o SysMood.exe -liphlpapi because the network module depends on the iphlpapi library. (CMake already links Iphlpapi automatically on Windows.)

Closes #7

Hi @AndersonTsaiTW. Apologize me, actually I have made some minor changes in main branch before reviewing your PR. Actually it was working completely fine ago with no conflicts, but it needed to be adhere to the new main branch which I actually changed after you have already submitted your PR. Sorry for inconvenience caused but can you rebase as per the latest main branch then it would be very helpful for me to review it and successfully merge it. I am again sorry for the inconvenience caused.

Regards,
Samman

Because this branch is kind of dirty, I built a new one and added the new feature again.
Please check the new branch. Thanks.
