Refactor the airrohr-firmware

[gideonmaina]

Make the codebase cleaner and leaner by refactoring/reorganizing these features among others:

1. Webserver components
2. Supported languages
3. WiFi configuration
4. Sensors libraries and functions
5. Loggers and displays
6. OTA update

The existing unstructured codebase is too long to follow along. Dumping almost all functionalities in a single file is not a good practice if code readability is to be achieved

Hey @augustinemwendwa72 / @usmanbiu I have refactored system configs to a go to a utils folder. This includes serial loggers, wif config, network time, helper functions ... etc
