I think you are making wrong use of the unpacked_to_packed block:

Your source is a file with bytes.
These should be considered "packed"
(i.e., bits are packed into a byte).

Thus you need to unpack them using
The output of this block will be bytes, each having
only 2 bits worth of data in them, sop they can be used
as inputs to the lookup table...
