* Intended usage is data validation in split transport code.
* Default space efficient algorithm.
* Opt-in fast table based algorithmn with #define CRC8_USE_TABLE switch.
* Define switches for size and speed optimized versions, the default is size
optimized by using uint_least8_t as datatype for calculations.
* #define CRC8_OPTIMIZE_SPEED uses uint_fast8_t as datatype for
calculations, this only affects 32-bit Archs like ARM and RISC-V.
* Placeholder crc_init() function for hardware backed crc calculation,
not implemented yet.
