Merge Request: Refactor and Enhance Request Handling, JSON Parsing, and Task Management

Summary of Changes:

Key Features:

• Refactor send_request_to_websrv_task to use std::map for parsed results, improving the handling of response data.
• Update JSON parsing by refactoring JsonParser to utilize std::map for key-value storage, improving parsing efficiency and logic.
• Enhance request handling with updated methods for improved response handling (sendRequest and parseResponseIntoJson).
• Improve task management by renaming and refactoring get_request_timer_callback to get_request_timer_task for clearer task handling and management.
• Update UART configuration to a baud rate of 115200 and improve debug log handling.
• Enhance RequestHandler with additional buffer length and improved response handling features.
• Add overloaded functions for instruction handling with various parameter types.

Notable Changes:

• Renamed send_request_task to send_request_to_websrv_task for clarity.
• Refactored the UART configuration and communication setup, adding better handling of debug logs.
• Improved SDcard class methods for string and binary file handling.
• Detailed updates to the README, including custom partition table instructions.

Additional Information:

• These changes also include improvements to error handling, system logging, and optimizations to the core task processing loop.
• These updates are intended to streamline communication with web services and enhance the overall performance of the system.
