Splitting out a frame of bytes

I like everything about this except the hard coded mask, you can tell from my previous posts that I am sold on calculating it. It would be clearer to be able to just define the data field length numerically, and let the software make the mask:

struct BitExtractor
{
  const uint8_t bitFieldLength;
  const uint8_t  offset;
};
...
const struct BitExtractor parameterAlfa    = {5, 9};
const struct BitExtractor parameterBravo   = {..., ...};
const struct BitExtractor parameterCharlie = ...;

The function getBits() can calculate a mask based on the math presented above.
