Refactor SerialCommand to support Stream interface and improve command handling

- Added readSerial(Stream &stream) method to allow reading from any Stream-compatible transport.
- Introduced readChar(char inChar) method for processing individual characters.
- Updated command matching logic to enhance debugging output.
- Improved buffer handling and command execution flow.

Enhance platformio.ini for better compatibility and added libraries

- Added NimBLE-Arduino and WebSockets libraries for BLE and WiFi support.
- Updated upload and monitor ports for better compatibility with macOS.

Integrate WiFi and BLE protocol interfaces

- Implemented startWebInterface() to initialize WiFi protocol alongside existing web server.
- Added BLE support with a new EggBot BLE Serial Protocol for command handling over BLE.
- Created WebSocket server for WiFi communication, maintaining compatibility with existing command protocols.

Refactor command handling in Functions.cpp

- Replaced direct Serial.print calls with protocolWrite for consistent output handling.
- Updated command registration to use a lambda function for better readability and maintainability.

Add documentation for EggBot protocols

- Created separate markdown files for BLE, WiFi, and Serial protocols detailing command structures and usage.
- Provided examples of command transactions for better developer guidance.

Implement BLE and WiFi protocol handling in respective source files

- Developed BLE_Interface.cpp for managing BLE connections and data transmission.
- Created WiFi_Protocol.cpp for handling WebSocket communication and data reception.
