Refactor: Consolidate duplicate PID controller implementations into a single module

[GaneshPatil7517]

tools/pidmayuresh.py and tools/pidmayuresh3.py implement the exact same PID controller with the exact same tryparam defaults, the same function signature pid_controller(state, ym, sp, Kp, Ki, Kd, sigout, cin, low, up), and the same logic. The only difference is pidmayuresh.py uses logging.debug() while pidmayuresh3.py uses print(). One of these files should be removed, or they should be consolidated.

hello @pradeeban can i raise PR on this.....

@GaneshPatil7517 sure, go ahead.

Also, all your bug reports have weird titles. I understand you may be automating the bug reporting from your IDE (VS Code or Google Antigravity). That is ok - but please go ahead and manually fix those bug report titles as it is an eyesore to read.
