MLBEDSW-8873: MLCE: Update LUT index calculation
- A network containing several softmax operators caused an
output diff
- The problem was that the code that detects if the LUT is
already in internal SRAM calculated everything correctly except
for which lut index to use.
- The code should use the slot_size and not then LUT size when
calculating the index which fixes this problem.
- Updated unit tests
