bugs fixed: - move global variables into device descriptor - guard bus access (use acquire and release) added functionality: - enable SPI mode structural improvements: - reduce stack usage - simplify the driver's structure - centralize bus access code - use assertions - cleanup includes - use shortcuts for bus access style changes: - fix line length - cleanup and improve doxygen - unify pointer notation (char *var over char* var) - unify (error) return messages - use `#ifdef MODULE_BME280` instead of `#if defined(BME..)` - unify debug messages -> using `[bmx28] x: msg` scheme
