   TIL: it's interesting that the driver interface table should always be the minimum amount of functions required to achieve the functionality that a user may need, because the linker cannot garbage collect the non-used functions from the table.
   
   In this proposal I have one interface function called `process` that does the same as calls to `start + update + finish`. Although I have not used `process` it still uses 200 bytes (about the same as the other 3 functions together). Since this can be trivially done in the upper layer, I will remove later.
