/**
 * @file config.h
 *
 * @brief Header file for configuration settings and EEPROM operations in the ChainLube application.
 *
 * This file defines configuration settings for the ChainLube project, including default values,
 * EEPROM structures, and functions for EEPROM operations. It also defines enums for different sources
 * of speed input, GPS baud rates, and CAN bus sources. Additionally, it includes functions for EEPROM handling
 * such as storing, retrieving, and formatting configuration data.
