Implement Centralized Logging System with Configurable Log Levels

[Shourya742]

Please refer to this comment: #60 (review).

Currently, the tool has scattered logging, where we are using println! for stdout in our proxies. We want to implement a tool-wide logger with the following levels: ERROR, DEBUG, INFO, and TRACE. This will allow users to select their preferred log level for better control over the tool's output.

Hi @Shourya742 is this just for the sv1 and sv2 proxies or is it everywhere in the codebase?
