Enhance llcc68 definitions with new bandwidth and coding rate enums

Browse Source 
- Added a new bandwidth enum value for 7.8MHz and corresponding string conversion function.
- Introduced a string conversion function for coding rates.
- Implemented a utility function to safely convert uint8_t to optional for spreading factors.
- Enhanced the modulation parameters structure with a to_string method for better representation.
